E2 PRESSURE TRANSDUCER
INSTALLATION MANUAL
WARNING! READ
⚠ ⚠
BEFORE INSTALLATION
A failure resulting in injury or damage may be
caused by excessive overpressure, excessive
vibration or pressure pulsation, excessive
instrument temperature, corrosion of the
pressure containing parts, or other misuse.
Consult Ashcroft Inc., Stratford, Connecticut,
USA before installing if there are any questions or concerns.
OVERPRESSURE:
Pressure spikes in excess of the rated overpressure capability of the transducer may
cause irreversible electrical and/or mechanical damage to the pressure 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 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 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 chamber
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 regardless of pressure
• In severe cases, there will be no output.

Prohibit freezing of media in pressure port.
Unit should be drained (mount in vertical
position with electrical termination upward) to
prevent possible over- pressure damage from
frozen media.
STATIC ELECTRICAL CHARGES:
Any electrical device may be susceptible to
damage when exposed to static electrical
charges. To avoid damage to the transducer,
observe the following:
• Operator/installer should follow the proper
ESD (electrostatic discharge) protection
procedures before handling the pressure
transducer.
• Ground the body of the transducer BEFORE
making any electrical connections
• When disconnecting, remove the ground
LAST!
Note: The shield and drain wire in the cable
(if supplied) is not connected to the transducer body, and is not a suitable ground.

DESCRIPTION
The Ashcroft® Model E2 is ideal for a broad
range of pressure sensing requirements
found in general and heavy industrial applications as well as applications in test
and measurement. The E2 offers a wide
variety of material, process and electrical
connections to meet your application requirements. It is designed for use with both
liquids and gases it provides an accurate,
reliable and highly repeatable output. This is
accomplished through the use of an onboard
microprocessor that is programmed during
a unique digital compensation process to
provide an extremely linear performance
over the entire specified pressure and temperature range.

INSTALLATION AND ASSEMBLY
All supply lines should be arranged so that
there are no mechanical forces acting on
the device.
For units with NPT type pressure fittings
apply Teflon
®
tape or an equivalent sealant
to the threads before installing. When tightening, apply a wrench to the hex wrench
flats located just above the pressure fitting.
DO NOT tighten by using a pipe wrench on
the housing.
Process connection:
• By authorized and qualified personnel only.
• All lines need to be depressurized when
the instrument is being connected.
•
Appropriate steps must be taken to protect the device from pressure surges.
•
Check the suitability of the device for the
media to be measured.
• Maximum pressures shall be observed.
• Check that all connections are tight before
use.
If during installation the pressure measuring
lines are already under pressure, the zero
point cannot be checked and no settings
can be adjusted. In these cases, the device
should only be connected electrically first.
Electrical connection:
• By authorized and qualified personnel only.
•
The electrical connection of the device
shall be performed according to local
electrical codes
•
Turn off power before connecting the device.
•
Connect only to Class 2 power supply

Noise
For minimum noise susceptibility, avoid running the transducers cable in a conduit that
contains high current AC power cables. Where
possible avoid running the cable near inductive equipment.
Shielded Cable
Units with shielded cable electrical termination, connect the drain wire to the guard
terminal on the read out device or measuring
instrument, if available. In all other cases
connect to the ground or to the power supply
negative terminal.

Offset and Span adjustments
1. WARNING! Disconnect the E2G transducer
from the control system prior to performing offset and span adjustments.
2. Activate calibration mode by first cycling
power off and on, and then within 30 seconds tap the Ashcroft calibration magnet
near the specified area on the E2G label.
The initial code to enter the calibration
mode is 1-3-1 (Tap the unit for one second, release. Tap unit for three seconds,
release, tap unit for one second, release).
When the calibration mode has been activated the output signal on the transducer
will drive from over range to under range.
3. At the offset pressure record output offset
to be used in the span adjustment in step
4. Increase pressure to 100% of span,
this will allow you to adjust the span of
the unit. The span is adjustable to +/- 5%
of full scale.
4. Tap the magnet near specified area on
the E2G label. Adjust span to desired span
value plus the offset value recorded in
step 3. (The span will increase from its
current value up to +5% of scale. Once
the output has reached the max value,
the span will jump to -5% and continue
to increase. (Note - holding the magnet
in position while adjusting the span will
increase the speed at which the span increases or decreases. Once you get close
to your desired setting you should tap the
magnet against the unit for finer adjustment. If you scroll past your desired value,
repeat step three until you have reached
your desired span value.
5. Decrease the pressure to 0% of span,
this will allow you to adjust the zero of
the unit. The offset is adjustable to
+/- 5% of full scale.
6. Tap magnet near specified area on the
E2G label. Adjust the offset to the desired
value. (The offset will increase from its
current value up to +5% of scale. Once
the offset output has reached the max
value, the zero will jump to -5% and continue to increase. (Note - holding the magnet in position while adjusting the offset
will increase the speed at which the offset
increases or decreases. Once you get
close to your desired setting you should
release the magnet and tap it against the
unit for finer adjustment. If you scroll past
your desired value, repeat step 6 until you
have reached your desired offset value.
7. Once you have completed step 6, you can
repeat step 3 through 6 to adjust or check
your calibration
8. Once you have verified the calibration, the
unit will exit the calibration mode after 30
seconds of magnetic inactivity. This will be
signaled by the output of the transducer
driving to over range, under range and
back to the normally calibrated output.
MAINTENANCE
The device does not require maintenance. In
order to ensure reliable operation and a long
