WARNING! READ BEFORE INSTALLATION

Fluid hammer and surges can destroy any pressure transducer and must always be avoided. A pressure snubber should be installed to eliminate the damaging hammer effects. Fluid hammer occurs when a liquid flow is suddenly stopped, as with quick closing solenoid valves. Surges occur when flow is suddenly begun, as when pump is turned on to full power or a valve is quickly opened.

Liquid surges are particularly damaging to pressure transducers if the pipe is originally empty. To avoid damaging surges, fluid lines should remain full (if possible), pumps should be brought up to power slowly and valves opened slowly. To avoid damage from both fluid hammer and surges, a surge chamber should be installed and

a pressure snubber should be installed on every transducer.

Symptoms of fluid hammer and surge’s damaging effects:

1. Pressure transducer exhibits an output at zero pressure (large zero offset). If zero offset is less than 10% FS, user can usually re-zero meter, install proper snubber and continue monitoring pressures.

2. Pressure transducer output remains constant regardless of pressure.

3. In severe cases, there will be no output.

HANDLING

This instrument is susceptible to damage when exposed to static electrical charges. To avoid damage to the sensor observe the following:

• Ground the transducer body before making any electrical connections.

• When disconnecting, remove ground connection last.

Note: If supplied, the braided shield in the cable is not connected to

the transducer’s body and is not a suitable ground.

MOUNTING

Although the units can withstand some vibration, it is always good practice to mount the sensor where there is minimum vibration. Use

Teflon

tape on NPT threads and install the wrench on hex flats. DO

NOT tighten by using a pipe wrench on the housing.

CALIBRATION

All models are tested to meet or exceed the published specifications. The calibration and testing was performed using instrumentation and standards that are traceable to the U.S. National Institute of Standards and Technology (NIST). We further certify that our calibration systems complies with MIL-STD-45662.

Each sensor comes calibrated and does not require recalibration. The zero and span pots are accessible through the top of the case. Loosen the four screws and separate the top carefully. The zero pot is marked with a white dot. Some models have the span pot on the side of the pull out board. Be careful of static charges when touching the board (span pot will be on the opposite side from the zero pot).
