4-20mA Guard, VM 500-4 SGP Model
7 Channel 4-20 mA Sensors Monitoring

Key Points

  • Monitor any type of sensor with 4-20ma output.

  • Monitor power, pressure, flow, humidity, temperature...

  • Receive a phone call or pager message with the integrated telephone dialer and digital voice if any sensor goes out of limits or the power goes out


Monitor seven sensors with 4-20ma outputs. Sensors are available from numerous manufacturers that can monitor temperature, flow, pressure, humidity, pretty much any parameter. This is the perfect product if you have a system or process that needs to be monitored 24/7/365 and someone notified about a fault condition immediately.
We can mount your 4-20MA Monitor in a NEMA 4 enclosure for you. The enclosure is 12"x12" and made of ABS plastic with a hinged smoked colored cover so you can see the display without opening the door. The enclosure also comes with air vents for cooling and knockouts for simple wiring and is lockable to prevent tampering. Consult us when ordering.
