MD-S828E digital pressure switch
80mm stainless steel shell dual group relay output MD-S series digital pressure switch
Product details
MD-S828E is an intelligent digital pressure switch with an 80mm stainless steel casing, which integrates pressure measurement, display, and control into an economical digital pressure switch.
MD-S828EA intelligent digital pressure switch is an intelligent digital pressure switch with multiple outputs,Built in temperature sensor temperature compensation, high display accuracy, diverse control output methods, dual relay output, RS485 output, 4-20mA signal output optional.
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.
