WARNING! READ
BEFORE INSTALLATION
A failure resulting in injury or damage may be
1. GENERAL:
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:

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

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.
* Use either V- termination on G2 with 4-20mA output
