Orange Research 1502 SERIES Heavy-duty Diaphragm Sensor for High DP Liquids or Gases

Heavy-duty Diaphragm Sensor for High DP Liquids or Gases
1502 SERIES

Our 1502 and 1533 models have a heavy-duty diaphragm that is designed for high differential pressures, to 300 psid. This extends the range of our diaphragm sensor DP line – much higher than the more sensitive 1516 model. Though heavy-duty, the diaphragms are still flexible and repeatable enough to match the ±2% accuracy of our other DP gauges.

Model 1502 is a gauge with a single switch option (uncovered), while our model 1533 is always supplied with up to two switches or a transmitter within a NEMA 4X enclosure.

A rolling diaphragm sensor separates the high and low pressure ports making these models popular for gases as well as liquids. There is no bypass between the two 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 and displays the reading on 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.

Note: Reverse pressure should be avoided with these rolling diaphragm models. If this occurs the diaphragm may not return to its original position.
