Series 800 Temperature Smartstat : Introduction
There are some temperature switching applications that are very demanding due to the need for :-
- Very high (or low) temperatures.
- High accuracy and repeatability.
- Very large (or small) switching differentials.
- High frequency switching operation.
- Low frequency switching operation (once per year).
- Regular need to change switching temperatures.
These requirements may exceed the capabilities of conventional mechanical temperature switches, the Smartstat was designed to overcome these problems.
- Smartstat RTD elements can be used to provide ranges from -200°C to 400°C.
- Typical repeatability is 0.1%.
- Two independent single-pole, double-throw (SPDT) relays are fitted in the Smartstat, the operating points of which can be set anywhere within the range. The switching differential can be set from 1 digit to 100.0% of range without loss of accuracy.
- Being almost entirely 'solid state' the Smartstat can provide up to 100,000,000 switching operations. It can respond to changes in temperature more rapidly than a mechanical temperature switch.
- With a mechanical switch testing the operation regularly is the only way to ensure that it is operating correctly. With the Smartstat the continuous temperature display serves to indicate that the device is operating correctly and will switch when required.
- Pushbutton calibration of switch setpoints can be carried out on site without additional test equipment or tools.
In addition to its function as a high accuracy temperature switch the Series 800 Smartstat also functions as a temperature transmitter and temperature indicator enabling significant cost savings as several instruments can be replaced with a single device.
