Pressure transducers:
Pressure transducers are used to measure and control the pressures in the unit. These electronic sensors deliver 0 to 5 VDC.
The transducers can be calibrated through the controller. The pressure transducers are connected to the IOBs.

Temperature sensors:
The system uses electronic sensors to measure and control the temperatures in the unit.
There are three types of temperature sensors, 5K thermistor, 10K thermistor and RTD (three wirings, MINCO S100308)
based on the IOB channel congurations.
