G2 & T2 PRESSURE TRANSMITTER

INSTRUCTION SHEET

WARNING! READ

BEFORE INSTALLATION

1. GENERAL:

A failure resulting in injury or damage may be

caused by excessive overpressure, excessive vi-

bration or pressure pulsation, excessive instrument

temperature, corrosion of the pressure containing

parts, or other misuse. Consult Ashcroft Inc., Strat-

ford, Connecticut, USA before installing if there are

any questions or concerns.

2. OVERPRESSURE:

Pressure spikes in excess of the rated overpressure

capability of the transducer may cause irreversible

electrical and/or mechanical damage to the pres-

sure measuring and containing elements.

Fluid hammer and surges can destroy any pressure

transducer and must always be avoided. A pressure

snubber should be installed to eliminate the damag-

ing hammer effects. Fluid hammer occurs when a liq-

uid flow is suddenly stopped, as with quick closing

solenoid valves. Surges occur when flow is suddenly

begun, as when a pump is turned on at 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 cham-

ber should be installed.

Symptoms of fluid hammer and surge's damaging

effects:

• Pressure transducer exhibits an output at zero

pressure (large zero offset).

• Pressure transducer output remains constant re-

gardless of pressure

• In severe cases, there will be no output.

FREEZING:

Prohibit freezing of media in pressure port. Unit

should be drained (mount in vertical position with

electrical termination upward) to prevent possible

overpressure damage from frozen media.
