High Precision Intelligent Control 4-20mA Digital Pressure Switch
MD-S 828E is an intelligent pressure switch, which has 2 independent relay outputs,each output has a normally open normally closed signal,and the return difference can be set independently
This series of products uses 304 stainless steel shell and connection, built-in high-precision pressure sensor, large-size bright four-digit LED display. The 4-20Ma/RS485 output is optional.
This series of pressure switches also have multiple functions such as one-key resetting, three unit switching, independent hysteresis setting, etc.
The design of the circuit pays attention to stability and fully takes into account the actual situation of the automation site. It has anti-dry magnetic interference, anti-surge protection, anti-reverse protection, etc.
The product adopts a compact all stainless steel shell, which is resistant to vibration, frequent impact, beautiful in appearance, sturdy and durable
Technicial Characteristics:
80MM diameter, 304SS shell
Radial and axial mounting
Different pressure units to choose, one key to zero clearing
Double relay output signal, each group with NO/NC, returning difference be set independent
Multiple connection modes, be used as controller, switch, digital electro connecting pressure gauge
