Relative humidity multi-parameter transmitter CS-WPT300G

pressuretemperatureHVAC

The CS-WPT300G is a fully welded pressure and temperature transmitter designed for refrigeration, air conditioning and heat pump systems. It is intended for refrigerant pressure measurement and system control, delivering industry-standard signal outputs and a leak-free welded construction suitable for demanding HVACR applications.

Features

• Integrated pressure and temperature transmitter
• Dual-channel 4–20 mA outputs
• Silicon-oil filled diffusion silicon sensor element
• Sealed gauge (gauge pressure)
• Fully welded construction (no O-rings)
• Anti-condensation design
• Forward and reverse overvoltage protection
• High measurement accuracy

Applications

• Maglev (magnetic bearing) units
• Chilled water screw chillers
• Water-source heat pump units
• Ground-source heat pump units
• Industrial refrigeration systems

Performance specifications (reference)

• Reference temperature (test condition): 20–25 °C
