Dwyer MHS series pressure switch 4-20 mA

 The Series  Dwyer  MHS   Explosion-proof membrane pressure switch is a 3-in-1          instrument

 

  

 

possessing a digital display gage, control relay switches, and a transmitter with current
output. Combining these three features allows the reduction of several instruments with oneproduct, saving inventory, installation time and money. The Digihelic® Controller is theideal instrument for pressure, velocity and flow applications, achieving a 0.5% full scaleaccuracy on ranges from 5 to 100 in w.c.

 

 

 

The Digihelic® Controller allows the selection of pressure, velocity or volumetric flow
operation in several commonly used engineering units. Two SPDT control relays with
adjustable deadbands are provided along with a scalable 4-20 mA process output. The Series
DH provides extreme flexibility in power usage by allowing 120/220 VAC and also 24 VDCpower which is often used in control panels.

 

 

 

Programming is easy using the menu key to access five simplified menus which provide
access to: security level; selection of pressure, velocity or flow operation; selection of
engineering units; K-factor for use with flow sensors; rectangular or circular duct for
inputting area in flow applications; set point control or set point and alarm operation; alarmoperation as a high, low or high/low alarm; automatic or manual alarm reset; alarm delay;view peak and valley process readings; digital damping for smoothing erratic process
applications; scaling the 4-20 mA process output to fit your application’s range;Modbus®communications; and field calibration.

 

 

 

With all this packed into one product it is easy to see why the Digihelic® Controller is theonly instrument you will need for all your pressure applications.
