Pressure transmitters

NSK and XSK

Pressure transmitters type NSK and XSK are
compact, lightweight sensors with piezo
resistive sensors to be used by OEM’s in
refrigeration and air conditioning units
for high and low pressure protection, fan
control, and diagnostic and performance
monitoring purposes.

NSK has a ratiometric output signal, 0.5 to

4.5 Vdc @ 5 Vdc supply.

XSK has a current output signal, 4 to 20 mA.

Features • Applicable up to 135 °C fluid tempera-

ture

• Degree of enclosure IP 66

• UL approved, UL file no E43867

• Light and compact design

• Absolute / sealed gauge sensor type;
1 atmosphere (1013hPa) is defined as
0MPa.

• Applicable with:

- R 410A

- R407C

- R404A

- R134 a

• Color coded electrical connection for
low and high pressure indication

- NSK: Round Packard

- green (LP)

- black (HP)

- XSK: Molex

- blue (LP)

- black (HP)

• Easy process connection

- ¼” female flare with depressor

pin as standard

- ¼” male flare port

• Available with solder connection
