Product Introduction
SPK21 12v 24v Negative Low Air Conditioner Pressure Sensitive
Controller Switch adopts all-stainless steel structure. The
pressure sensing components are automatically tested by computer.
The laser calibration process compensates the zero point and
temperature performance over a wide temperature range, which
enhances the long-term stability of the transmitter in industrial
environments. It adopts laser welding technology, safe and
leak-free.
