Ashcroft T2 - High Performance Pressure Transmitter - Manual

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.
