All welded pressure transmitter compatible with R22 & R410A refrigerants. Withstands up to 400 psig. Durable stainless steel construction. Versatile solution for refrigeration pressure monitoring.
The 17.609G is an all-welded pressure transmitter designed specifically for refrigeration applications using R22 and R410A refrigerants. It’s built to withstand pressures up to 400 psig, making it suitable for a variety of refrigeration systems. The all-welded design ensures no internal elastomeric seals are exposed to the refrigerants, enhancing the sensor’s reliability and longevity.
A key feature of the 17.609G is its compatibility with both R22 and R410A refrigerants. These refrigerants are commonly used in residential and commercial air conditioning and refrigeration systems. The 17.609G’s compatibility with both refrigerants makes it a versatile choice for technicians and installers. It eliminates the need for separate pressure transmitters for different refrigerants, simplifying installation and maintenance.
The 17.609G is designed for direct refrigerant pressure measurement, providing accurate readings for system monitoring and control. The output signal, 4-20mA, is standard for industrial instrumentation, allowing easy integration with existing control systems. The 2-wire configuration simplifies wiring and reduces installation costs.
The stainless steel construction (316Ti for the process connection and 304 for the housing) provides excellent corrosion resistance, crucial for withstanding the harsh conditions often found in refrigeration environments.
The 17.609G pressure transmitter is a robust and reliable solution for pressure monitoring in refrigeration systems using R22 and R410A refrigerants. Its all-welded design, compatibility with both refrigerants, high accuracy, and durable construction make it an excellent choice for installers, technicians, and OEMs.
