Description
The OE258 Building Static Pressure Sen-
sor is used to sense building pressure in
applications where monitoring of the
building static pressure is required to in-
sure the building maintains the proper air
pressurization.
The OE258 Building Pressure Sensor
case is molded from fire retardant glass
filled polyester. The sensor utilizes a ten-
sioned stainless steel diaphragm and in-
sulated stainless steel electrode. This
arrangement allows up to 10 PSI over-
pressure without damage to the unit. The
sensor provides a 0.0 to 5.0 VDC output
in response to a –0.25 to +0.25 inch WC
pressure differential. Accuracy is
±
1% of
full scale of the sensor.
For easy wiring the OE258 Building Static
Pressure Sensor has (3) 6-32 screw ter-
minal wiring connectors. The sensor has
(2) ¼” barbed fittings provided for the
connection of tubing to the high and low
pressure ports.
The OE258 Static Pressure Sensor is
designed to be mounted to a flat surface
by means of the (2) 0.156 diameter holes
provided in the sensor casing. For accu-
rate readings the sensor must be
mounted in a vertical position.
