MD-S928Z Axial Digital Pressure Switch
8-core outgoing line, dual independent relays, 100mm stainless steel casing, axial installation MD-S series digital pressure switch
Product details

MD-S928Z is an intelligent digital pressure switch with axial installation, which integrates pressure measurement, display, and control.

This series of pressure switches can be equipped with two normally open and normally closed alarm points, as well as two high and low pressure controls. In addition, it has multiple functions such as one key reset and switching between three display units.

The design of the circuit emphasizes stability and fully considers the actual situation of the automation site, with strong resistance to dry magnetic interference, surge protection, anti reverse connection protection, etc.

The operation method of this pressure switch is simple and intuitive. Simply set the action point and hysteresis according to the manual. The hysteresis of the two sets of relays can be set independently. According to the customer's site, only one group can be used for control, or both groups can be used together. All products use food grade 304 stainless steel joints and 304 stainless steel shells, providing different axial and radial installation methods.
