TURCK sensors provide important information for efficient industrial automation, such as discrete and analog position signals, level control, flow rates, temperatures, speed and directional feedback. TURCK offers more than 5,000 proximity sensors based on inductive, capacitive, or magnetic principals of operation, along with ultrasonic, flow, linear and rotary position sensors to implement your made-to-measure solutions. It is good engineering practice to mount sensors horizontally or with the sensing face looking down. Avoid sensors that look up wherever possible, especially if metal filings and chips are present. In many cases sensors have to be mounted in close proximity to fulfill the monitoring work. In order to avoid mutual interferences, TURCK offers the Q10S-ZP shield. The locknut torque should be considered for all threaded sensors to prevent the housing from being over stressed.
Capacitive sensors utilize a non-contact sensing technology that detects a wide variety of materials. These sensors make use of a compensation electrode, and most come with sensitivity adjustments that allow a designer to tune out certain materials such as glass or plastic, making this type of sensor a common choice for point level applications. One of the major benefits of capacitive sensors is their ability to sense through low-dielectric materials. With the sensitivity properly adjusted, these sensors can be used to "see through" an object wall to detect its contents. In addition, capacitive sensors have the ability to sense most materials including wood, plastics, cardboard, glass, grain, all metals and most fluids.
Flow sensors from TURCK are a versatile family of products with the ability to use either insertion or in-line designs to measure flow. These sensors are available as a calometric design that is best suited for monitoring flow, or as a magnetic inductive which functions as a flow meter. TURCK flow monitors are solid-state devices. The monitors do not include any moving parts that may break or become lodged in the pipeline, as is often the case with mechanical devices that come in contact with the media being sensed.
Inclination sensors are a mems based sensor family that provide angular measurement relative to gravity. Depending on the sensor selected, these sensors are capable of single axis (up to 360°) or dual axis (X-Y) measurement angles ranging from 5° to 85°. Output choices include analog voltage, analog current, PNP, IO-Link, and CANopen. Inclinometers measure angular tilt in reference to gravity. TURCK inclinometers contain a MEMS (Micro-Electro-Mechanical System) device that incorporates a microelectromechanical capacitive element into the sensor that utilizes two parallel plate electrodes, one stationary and one attached to a spring-mass system. The suspended electrode is free to move with the change in angle relative to earth's gravity. This results in a measurable change in the capacitance between the two plates that is proportional to the angle of deflection. These signals are conditioned to provide voltage outputs (0.1 to 4.9 VDC) or current outputs (4 to 20 mA).
Over the last 50 years, TURCK has built a reputation for designing and building reliable non-contact inductive sensors that are widely used in diverse positioning applications. Due to TURCK's extensive experience, we have created a broad product portfolio that enables a designer to find the sensor that fits the application. TURCK portfolio includes standard inductive sensors as well as patented sensing technologies like uprox, which sense all metals at the same range and at greater ranges than standard inductive sensors. TURCK inductive proximity sensors are manufactured with a shielded coil, designated by "Bi" in the part number, and a nonshielded coil, designated by "Ni" in the part number. Embeddable (shielded) units may be safely flush-mounted in metal. Nonembeddable (nonshielded) units require a metal free area around the sensing face. Because of possible interference of the electromagnetic fields generated by the oscillators, minimum spacing is required between adjacent or opposing sensors.
TURCK’s linear position sensors are available in a variety of sensing technologies that provide a designer with a variety of options when deciding which solution best fits the application. Inductive linear position sensors are non-contact sensors using the R-L-C principle of operation, with measuring ranges up to 1,000 mm. Magnetic linear position sensors are non-contact sensors using external magnets with imbedded hall effect sensors measuring ranges up to 200 mm. Magnetostrictive linear position sensors are non-contact sensors using external magnets measuring ranges up to 300 in. Draw wire (or cable pull) are mechanically operated devices with measuring ranges up to 40 m. WIM Analog Magnetic field sensors are used with external magnet that move parallel to the sensor face. The WIM products come in several packages which can be used with the pneumatic cylinders that incorporate a magnet, or a magnet mounted on moving assembly. The sensing range is determined by the field of strength of the magnet.
TURCK magnetic position sensors are typically used on pneumatic cylinders that have internal magnets and non-ferrous housings. TURCK has developed a number of different sensor housings and accessories that allow a designer to mount a BIM sensor on all common pneumatic air cylinders. In addition, we offer barrel sensor housings that can be used with external magnets for position applications. TURCK permaprox cylinder position sensors are used for the detection of magnet equipped pistons on pneumatic and other types of cylinders. These non-contact sensors are able to determine the position of the cylinder piston without diminishing the integrity of the cylinder itself. This allows the ensors to operate without intruding upon the cylinder, keeping the system completely intact.
Pressure sensors from TURCK capture relative or absolute pressures in liquids and gases. The PS series offers display, showing measuring ranges from vacuum to 600 bar. Outputs include set point, analog, and IO-Link. The PT series are transmitters without displays, measuring from vacuum to 7,500 PSIG. Outputs include 2 wire current and 3 wire analog voltage. The PK series offers display, and is specially designed for pneumatic or vacuum applications. Measuring ranges are either vacuum or 145 PSIG, with dual PNP outputs. The PC series are pressure switches with dual PNP outputs or IO-Link communication.
TURCK rotary position sensors are available in a non-contact rotary inductive sensor, as well as optical and magnetic encoders that offer a variety of options when deciding what solution best fits the application. Inductive rotary position sensors are non-contact sensors using the R-L-C principle of operation with a choice of analog, incremental, SSI, or CANopen interface. Optical encoders are available in shaft or hollow shaft, a variety of sizes and interfaces including incremental outputs and absolute protocols. Magnetic encoders are available in shaft or hollow shaft. Draw wire (or cable pull) are mechanically operated devices with measuring ranges up to 40 M.
TURCK offers a large selection of accessories for operation, mounting and protection of sensors. The range comprises functional accessories and actuators, mounting accessories for simple and safe mounting as well as protective aids for protection against mechanical load.
Temperature sensors from TURCK offer tailor-made solutions via displays, simple programming, and flexible process connections. These sensors are available as 100 ohm platinum RTD, RTD transmitters with and without IO-Link, and temperature transmitters with display. TURCK’s temperature instruments utilize platinum resistance temperature detectors (RTDs), commonly referred to as a Pt-100 technology. Pt-100’s contain a platinum wire that is wrapped around a core or patterned as a thin film on a substrate so that it experiences minimal differential expansion or other strains. As the temperature changes, the controller measures the change in the electrical resistance of the platinum wire. The resistance experienced by the sensor is proportional to the temperature changes being experienced by the media being sensed. Specifically, the hotter the wire becomes, the higher the value of electrical resistance. They require a small power source in order to measure resistance.
TURCK ultrasonic sensors are non-contact sensors that use sound waves to sense the target, making these sensors very versatile in solving both position and linear position applications. The ultrasonic sensor family has many options, including rectangular and barrel designs with set point, analog and/or IO-Link outputs. The sensor emits an ultrasonic pulse that reflects back from any object entering the sonic cone. Because sound has a constant velocity at a given temperature and humidity, the time taken for this echo to return to the sensor is directly proportional to the distance of the object. The sensor's output status is dependent on the comparison of this time with the setting of the detection zone.
TURCK’s dual sensors reduce installation costs and minimize the cost of maintenance. These robust and impact resistant sensors are ideal when valve position information must be provided. TURCK DSU35 valve sensor and target puck are highly resistant to harsh chemicals, and may be mounted to several different actuator sizes without the need for adapters or spacer plates. The DSU35 is available with a terminal chamber, which is often required in chemical process applications where conduit must be used. TURCK DSC26 sensor uses injectionmolding technology to ensure that it is fully sealed and well suited for use in wet applications. It is resistant to high pressure cleaning with aggressive cleaning agents.
