Watlow is a leading supplier of integrated multi-function, process and temperature controllers, limits and scanners, power switching devices, agency-rated safety limits, operator interface terminals, process and event data loggers and recorders and accessories to reliably implement and control a complete thermal system.
Watlow Indicators
Watlow's temperature and process indicators are ideal for displaying measurements of temperature and other process variables; such as flow, pressure and relative humidity. They are moisture resistant and include bright, four-character LED displays, user-selectable temperature units, sensor break protection, agency approvals including UL®, CE, RoHS compliance and multiple mounting options such as DIN-rail or panel mount configurations.

Integrated Multi Function Controllers

Watlow's integrated multi-function controllers decrease design and assembly time, require less space, minimize system complexity and best of all, lower the total cost of ownership.

Integrated multi-function products are modular and consistent in features, capabilities and specifications across the range of models. Using this product family helps users adapt to changing requirements because options can be added and models can be switched with minimal investment in learning, design, documentation, startup, commissioning and training. EZ-ZONE® controllers allow control loops and limits to be added in single increments as well as a variety of power switching options. They also allow for easy transfer of wiring from one product to another (consistent termination labeling).

The broad feature set includes standard bus communications, TRU-TUNE®+ adaptive control, timer and counter application blocks, on-board data logging, user-customizable menus and SENSOR GUARD backup to protect loads should a sensor fail. Other features include front-removable electronics, AUTO CLONE configuration backup and restore, NEMA 4X/IP66, Class I, div 2 rating, SD card expandable data logging memory, universal serial bus (USB) connectivity and free configuration software.

Power Controllers

Watlow solid state power switching devices complement the rapid switching required by PID temperature controllers and help deliver optimum system performance and service life. They are available in 1-phase and 3-phase/2-leg and 3-leg configurations, feature touch-safe terminations, input indicators, zero-cross, random or phase-angle fire options, ratings from 18 to 1,000 amperes and agency approvals including CE and UL® 508. Various configurations offer short circuit current ratings (SCCR) of 200,000 amperes, extensive system and heater diagnostic capabilities, heater bake out, integrated heat sinks, on-board fuses, RoHS compliance and serial communications.

Watlow DIN-A-MITE® and E-SAFE II power switching devices provide convenient DIN-rail mount packages and are a good replacement for mercury displacement relays.

Additionally the EZ-ZONE ST offers an integrated temperature and process controller with optional over- and under-temperature limit and safety shutdown contactor.
