Temperature controller range from AWE Ltd for the measurement and control of temperature in process applications

Temperature Controller

A temperature controller is a device designed to offer automatic control of a process based on the measured temperature value.

Each of the temperature controllers amplifies the incoming signal from a resistance temperature device (RTD) such as a PT100 or PT1000 platinum resistance thermometer (PRT).

The temperature is displayed on the screen of each of the temperature controllers allowing the user to visually identify the measured temperature.

Temperature Control Options

With the accurately measured temperature displayed on the screen the temperature controllers offer a number of different control options.

Each of the temperature controllers has a control relay. This is in an electrical contact which allows process devices to be switched on or off. This is commonly used to control heaters, chillers, as well as open or close control valves.

On effluent discharge monitoring systems the temperature controllers have been used open a control valve, allowing process effluent which is hotter than an agreed consent to discharge agreement to be recirculated. This allows the effluent to cool below the permitted temperature outlined in a consent to discharge agreement before being discharged.

Many of the controllers have 2 x control relays and the TR7615 has 2 x control relays and an alarm relay. This allows them to control numerous processes and are frequently used in process control applications in a number of manufacturing processes.

Temperature Controller with 4-20mA Output

In addition - to a control relay and associated set-point, many of the temperature controllers include a 4-20mA output.

This is an industry standard current signal which is proportional to the range of the instrument. So if an instrument has a range of 0 - 100°C and the measured value is 50°C - the 4-20mA signal would be 12.00mA.

In addition to temperature controllers with a 4-20mA, we also offer a stand alone 4-20mA temperature transmitter the TT100. This is designed to be mounted inside the head of a temperature sensor and transmit a 4-20mA signal directly from the temperature sensor itself.

Temperature Controller Range


TT100

TT100

The TT100 is a 4-20mA temperature transmitter - so not technically a temperature controller at all!

Designed to sit inside the head of temperature sensor, the TT100 takes the incoming signal from a  PT100 PRT and outputs a 4-20mA corresponding the measured temperature. Ideal for use with 4-20mA controllers and PLC's.

The TT100 is available with a measuring range of 0 - 50°C, 0 - 100°C0 - 200°C, or -10°C to 100°C.

TR3645

TR3645

The TR3645-W is a surface mounting temperature controller with a range of - 20.0°C to 120 °C and is suitable for use with a 3 - wire PRT including a PT100 or a PT1000.

The TR3645 has a user adjustable set-point and associated control relay, and can provide a 4-20mA output.

Ideal for use in process control applications where the control relay can be used to active or deactivate process control equipment, and the 4-20mA is ideal for relaying the temperature signal back to a data logger or BMS (building management system).
