TEMP CONTROL PROPORTIONAL 0-100 20F

DIGITAL PROGRAMMABLE PROPORTIONAL TEMP CONTROLLER, INTERNAL OR EXTERNAL CAPNOGRAPH OPTION, 20 ft capillary clamp-on sensor, PROPERTY OF HONEYWELL

This is a Proportional Temperature Controller. It does not require a set point; the output will range from 0-100% of the set output, and it does this in response to its sensing element. The sensing element could be the temperature of the room, or a pool of water, or a block of metal. It is adjustable for length and for the type of fluid used in the sensing chamber. When installing this in a heating system, you will need to use an entirely separate pump installed outside of any tank or vessel with your heating coils. The heating coil can be straight steam, or heat pump.

The W3070 Series is designed to be used with a wide variety of liquids which do not foul or deteriorate the sensing element. Also, these proportional temperature controllers can be used with hot or cold water.

Advanced features for precision control of your process. The first proportional temperature controller to deliver true process capability, providing 1% of reading accuracy for lower cost and better quality. Ideal for a wide variety of processes requiring temperature control: incubators, water baths, hot plates, ovens, heating and cooling coils, and more.

An accurate and economical proportional type temperature controller for automatic process control applications. It provides a complete four function controller system that requires a minimum number of external components which makes wiring easy and economical.

The Proportional Control Thermostats provide long term control of small temperature changes. They are designed to provide accurate , stable, troublefree operation for many years with minimum maintenance. They are especially suitable for water system applications, where they react quickly to changing demands and require no auxiliary temperature sensing devices.

Proportional controllers are actuated by a difference between the set point and the actual, sensed temperature. The Proportional Controller 3070 was designed for grow rooms where the incoming air temperature is much warmer than the desired air temperature. Its design is based on many years of experience building high quality controllers. The Proportional Controller 3070 has an integrated Micro-Processor that allows you to program the unit using either manual buttons or a computer interface.
