These digital thermostats can also be used as replacements for normal capillary thermostats as the prices are now comparable.
The Novus N322 digital controller offers PID and on/off control for heating and refrigeration purposes with 2 independent setpoints. They are suitable for PT100, Pt1000, T/c J & K, NTC, PTC.

The Novus N321R is a thermostat dedicated to applications in refrigeration. The defrost cycle is accomplished by turning off the compressor at time intervals chosen by the user. Pt100, Pt1000 and thermistor sensors inputs available. Adjust for ON and OFF durations. Auto defrost at programmable intervals. Manual Defrost key on the front panel.

The West 6100+ offers all the functionality of the popular 6100 with some enhancements and time saving features. The same compact format that even fits in the SAME CASE as the old 6100, so instrument upgrades can be easily performed without wiring changes.
The universal input is freely configurable to TC/RTD/mA/V/mV and can be ordered as "Default" (set for a "J" type thermocouple input) or preset to your exact requirements.
The main control output is now a plug in option board and can be specified as either
Relay, Logic, Analogue or Triac. The analogue output may be configured to 0/4-
Please note that the Output slot 1 board is different to the Output slot 2 and 3 boards.

Thermocouples, PT100 and thermistors are used where the measurement of a process temperature is required. In general PT100 and PT1000 are more accurate over larger temperature spans and thermocouples are generally more cost effective.
We offer many sizes from stock, if not stock we can supply them in days if required.
Common styles
- Probes
- Bayonet
- Assembly DIN B heads
- Flanged
- Sleeved
- Eyelet/Washer
- Surface mount
- Leaf
The most common thermocouples are K and J. Common PT100 probes both 2 and 3 wire designs.

We offer a range of single and three phase solid state relays available for chassis or Din mounting. They are supplied with a protection cover and LED indicator.
Please call for more details.
We can supply bespoke control panels to suit a variety of control applications suitable for wall and floor standing.
Features and Applications
4-
- Installations where there is a risk that the sensor could be damaged by overheating,
for example in semi-
automatic road repair machinery or on infrared- heated moulding/forming machines.
- Installations where there is a risk that the lens might become frosted over if the
sensor temperature drops below 0°C, for example on road-
gritting lorries or on ground- survey aircraft.
- In glass houses, where leaf temperature is monitored to detect changes in growth phases and sensor temperature can be used to detect changes in ambient temperature.
- On race tracks, where the sensors are mounted on overhead gantries and bridges to measure the track surface surface and detect changes in ambient temperature.
- In ice rinks, where the sensors are suspended from the ceiling and measure the ice surface and changes in ambient temperature.
- For forest fire detection, where a remote-
mounted sensor can give warning of excessive temperatures either on the ground or in the air.
- For thermal mapping inside large-
scale temperature- controlled storage facilities.
