Orange Research 1500/1800 SERIES Diaphragm Sensor for Liquids or Gases

Diaphragm Sensor for Liquids or Gases
1500/1800 SERIES

Select these diaphragm sensor models where low differential pressures exist. The popular 1516 model measures from 0-1 psid up to 0-50 psid. Our 1800 series models include our most sensitive diaphragm which can measure from 0-5" H2O to 0-8 psid. We also offer compound range models with a zero center.

The diaphragm sensor separates the high and low pressure ports making them popular for gases as well as liquids. There is no bypass between these ports as with our piston models.

As differential pressure changes the diaphragm sensor magnet moves proportionally. This movement is tracked by a pointer magnet, which rotates, relaying the reading onto an easy-to-read 2.5 to 6 inch dial.

Select from a variety of options such as follower pointers, red arcs and mounting brackets along with switch, relay or transmitter outputs.

• Low DP ranges at high line pressures, down to 0-5 inches H2O
• Rugged, weatherpoof design
• Gauge, switch and transmitter versions
• Popular in filtration, flow and level measurements
