3.2. Sensors
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.
For 19DV are the following three types of pressure transducers supported: Tianmu, TEXAS, Sensata.
Evaporator pressure
transducer
This transducer measures the pressure of the
evaporator.
Standard for
19XR2~E/V/D, 19XR6/7
and 19DV
Condenser pressure
transducer
This transducer measures the pressure of the
condenser
Standard for
19XR2~E/V/D, 19XR6/7
and 19DV
Economizer pressure
transducer
This transducer measures the pressure of the
economizer
Oil supply pressure
transducer
This transducer measures the oil pressure in
the oil discharge piping
Standard for 19XR2~E/V/D
and 19XR6/7
Oil sump pressure
transducer
This transducer measures the Oil pressure in
the oil sump
Standard for 19XR2~E/V/D
and 19XR6/7
This transducer measures the pressure of
pump output
This transducer measures the pressure of
bearing outlet
This transducer measures the pressure of
bearing inlet
This transducer measures the pressure of
pump input
Evaporator water
pressure difference
transducer (Option)
This optional transducer measures the
evaporator pressure difference between
entering and leaving water.
Optional for 19XR2~E/V/D,
19XR6/7 and 19DV
Condenser water
pressure difference
transducer (Option)
This optional transducer measures the
condenser pressure difference between
entering and leaving water.
Optional for 19XR2~E/V/D,
19XR6/7 and 19DV
Evaporator entering
water pressure
transducer (Option)
This is an option transducer, and it measures
the pressure of evaporator entering water
Optional for 19XR2~E/V/D,
19XR6/7 and 19DV
Evaporator leaving
water pressure
transducer (Option)
This is an optional transducer, and it
measures the pressure of evaporator leaving
water
Optional for 19XR2~E/V/D,
19XR6/7 and 19DV
