–10 ºC < Ta < 50 ºC
Refer to manual for use and
safety precautions.
For use only
in non-hazardous
locations.
WARNING
!
Fire or explosion hazard
DANGER
!
▪Do not use General Purpose versions in hazardous areas.
▪Do not use General Purpose versions in areas that may

Sensors
Use two wrenches to install or remove pressure connections
Connection: 1/8” female NPT, 316L SS.
▪Always use a 3/4 in. wrench on the pressure manifold when
you install or remove the 1/8 in. NPT fitting.
▪Applying torque to the manifold can damage the plastic
enclosure and voids the warranty.
▪Do not over tighten.
Carefully equalize the pressure
Avoid these two issues with dierential sensors:
1. Connecting pressure to the incorrect pressure port on DN
dierential pressure modules may cause damage to the
pressure sensor.
2. Applying pressure to either port before both connections are
made.
NOTICE
Apply pressure to both dierential ports at the same time.
Note: See Overrange limit in the section called Specifications
concerning overrange pressure limits. If over pressure damage
occurs, you must return the digital calibrator to the factory for
sensor replacement.
