PT5 Pressure Transmitters convert a pressure into a linear electrical
4 .. 20mA output signal suitable for controlling simple compressor
and fan switching to the more sophisticated application of
superheat modulation of Electronic Control Valves.
With competitive performance to price characteristics and an easy
to install pre-fabricated M12 cable assembly, PT5 transmitters
are the designers choice for all heat pump, refrigeration and air
conditioning applications.
• Piezo-resistive sensor with output signal 4 to 20 mA and
2-wire connection for the precise operation of superheat,
compressor or fan control systems
• Specially calibrated pressure ranges with ±1% accuracy
performance to fulfill demands of today’s refrigeration and
HVAC applications
• Fully hermetic
• PT5-xxM with 7
⁄16”-20UNF pressure connection and Schrader
valve opener
• PT5-xxT with 6mm x 40mm stainless steel tube and
integrated brazing neck for easy mounting in applications
requiring a fully hermetic system solution
• PT5-150D with pressure connection 1
⁄4” NPT (M) suitable for
subcritical and transcritical CO2
• Vibration, shock and pulsation resistant
• Protection class IP65 / IP67 (type-specific)
