11.6 Absolute Pressure Transducer

The control unit is fitted with three pressure transducers, one for the control and
monitoring of chamber pressure, the second for the control of jacket pressure and
the third for gasket pressure.

The transducer type IMT 3296 is a membrane pressure sensor and electronic
measuring circuit, having the following specifications:
Pressure gauge: 0-4bar abs.  
Output span current: 4-20mA
Supply voltage: 10V to 30V
The pressure of the steam to the gasket should be 3 bars (45 psi), but the
transducer is set at 1.5 bars (22 psi).

The terminals at the connector of the device are 1 (+24V) and 2 (OUT) to the
controller output.
