Mating connection cable assemblies are available as an accessory part
from NOSHOK. Refer to Electrical Connector Terminal Wiring and Pinout
for additional detail.
A pressure snubber may be installed to eliminate damaging hammer
effects. Water and conventional cleaning detergents are acceptable
cleaning agents. Cleaning with unsuitable cleaning agents may damage
the instrument or the product label. Do not use any aggressive chemical
agents or abrasive cloths or sponges.
Transmitter should be electrically common with earth via the process
connection.
• Refer to Power Supply Requirements and Ratings.
• Refer to Electrical Connector Terminal Wiring and Pinout.
• Refer to product technical specication for allowable minimum and
maximum temperature and pressure conditions.
General Operation
Pressure spikes in excess of the rated overpressure capability of the
transmitter may cause irreversible electrical and/or mechanical damage
to the pressure measuring and containing elements. Fluid hammer and
surges can destroy any pressure transmitter and must always be avoided.
Maintenance and Service
NOSHOK PT41 pressure transmitters are precisely calibrated, and
temperature compensated at the factory to ensure long and stable
performance.
The NOSHOK PT41 is capable of being eld adjusted for zero offset and
span by removing the top cap and adjusting the potentiometers. This
product is maintenance-free. Repairs should only be carried out by the
manufacturer.
Additional Notes
Any electrical device may be susceptible to damage when exposed to
static electrical charges. To avoid damage to the transmitter, observe the
following:
• The circuitry of the NOSHOK PT41 pressure transmitters is designed
to minimize the effect of electromagnetic and radio frequency interference.
To minimize susceptibility to noise, avoid running the termination
wiring in a conduit which contains high current AC power cables.
• Where possible avoid running the termination wiring near
inductive equipment.
NOTE: The shield and drain wire in the cable (if supplied) is not
connected to the transmitter body and is not a suitable ground.

Power Supply Requirements And Ratings
PT41 Series
High Pressure Fixed Range Transmitter
General Description
NOSHOK PT41 pressure transmitters are high performance instruments
intended for use in industrial applications where the process media is
compatible with the 316 Stainless Steel wetted parts and system
temperatures and pressure are within the limits specied herein.
Installation
NOSHOK PT41 pressure transmitters require no special mounting
hardware and can be mounted in any orientation with negligible
position error.
Although the units can withstand considerable vibration without damage
or signicant output effects, it is always good practice to mount the
transmitter where there is minimum vibration. Refer to product
specication for allowable shock and vibration conditions.
When installing or removing the unit apply a wrench to the hex wrench
ats, located above the pressure tting. A 27 mm wrench can be used
on the wrench ats of the hex.
WARNING
Please read the entire user manual for safe use of product.
NOTE: If NOSHOK PT41 Series High Pressure pressure transmitters are used in a
manner not specified in this manual, the protection provided by the equipment may
be impaired.
NOTE: The safety of the system is the responsibility of the assembler of the system.
See www.noshok.com for further product detail and documentation.
