![]() ![]() Accuracy: 0.35%FS 0.4 bar range min, 0. The cost to recharge a home A/C depends on the cause of the refrigerant leak and refrigerant prices, which are dependent on the unit and your location.The internal materials exposed to the measurement media are all welded stainless steel to protect the sensor from refrigeration coolants.Ī DIN plug external connection is provided to the 4 to 20 milliamp analog output for sending pressure readings to other nearby instrumentation. This DS 200 digital pressure gauge with 4-20mA output is powered by an external power source and is connected to the physical pressure measurement point using a G1/2 male thread process fitting. Digital display pressure gauge with 4-20mA output for pipe mounted use in refrigeration coolant measurement applications, capable of measuring 0 to 500 mbar g pressure with 1% accuracy and connected using a G1/2 male fitting.Ī combined digital readout unit and pressure sensor for mounting on a pipe to measure refrigerant pressure over 0 to 500 millibar gauge to an accuracy better than 1%. As nouns the difference between coolant and refrigerant is that coolant is a medium, usually fluid, used to draw heat from an object while refrigerant is a substance used in a heat cycle that undergoes a phase change between gas and liquid to allow the cooling, as in refrigerators, air conditioners, etc. ![]()
