With the SMARTPRESSUREGATE SPG501, the high and low pressures in refrigeration systems can be monitored and, with the aid of switching outputs, be regulated and output as alarms.
Via the RS485 interface, the SPG501 can be read out and configured by means of Modbus RTU.

Can be used for refrigerants R22, R134a, R404a, R407c, R407f, R410a, R507. Any other use is considered
a non-intended use.
