OPERATING & INSTALLATION INSTRUCTIONS
SERIES 2200/2600
PLEASE READ CAREFULLY BEFORE INSTALLING
Part Number: 560550-0064 Issue: F
INTRODUCTION
The Series 2200/2600 pressure transducers use molecularly bonded high output strain gauges to
provide 100mV output for full range pressure, when used with a 10V d.c. power supply.
Series 2200/2600 high output pressure transducers and transmitters are fitted with an Asic
providing various optional (at time of order) voltage outputs, and a 4-20mA current output
capable of being used in control and indicating loops without further amplification.
Series 2200/2600 with the CE Mark conform with the essential protection requirements of the
EMC Directive 2004/108/EC amended by certified type testing to EN 61326-1 and
EN 61326-2-3.
Series 2200/2600 with the CE0086 mark also complies with the requirements of the Pressure
Equipment Safety Regulations 2016 and can be used as part of a safety-related system on
Category IV pressure equipment.
HAZARDOUS PRODUCTS
The Consumer Protection Act of 1987, Section 6 of the Health and Safety at Work Act 1974 and
the Control of Substances Hazardous to Health Regulations 1988 require that we advise
recipients and users of our products of any potential hazards associated with their storage,
handling or use.
The products which our Company supplies may be classified as Electrical, Electro-Mechanical
and Electronic equipment.
These products are tested and supplied in accordance with our published specifications or
individual special requirements that are agreed in writing at time of order. They are constructed
so as not to affect adversely the safety of persons and property when properly installed,
maintained and used by qualified personnel, in the applications for which they were designed and
manufactured.
Conformity with the requirements of the CE mark only applies when the installation
conditions described in these instructions have been met. For units supplied without a
cable assembly connection to the transducer must be accomplished using Gems Sensors
approved cable. See APPROVED CABLE section.

GENERAL
* Transducer should not be subjected to greater than the maximum allowable pressure
(P.S.)
/ Temperature (T.S) as defined on the transducer label.
* Transducer should not be subjected to mechanical impact.
* In the event of fire the end user must ensure that the system pressure is vented to a safe
area.
* The effects of decomposition of unstable fluids should be considered by the user when
placing this device in service.
* The pressure transducer has no means of draining or venting, this must be performed by
another component in the end users system.
* Pressure range must be compatible with the maximum pressure being measured.
* Pressure media must be compatible with the transducer/transmitter wetted parts listed in
these instructions.
* Liquid must not be allowed to freeze in the pressure port.
* The gasket must be fitted under the electrical connector.
MECHANICAL INSTALLATION
Mounting: Pressure Transducer is designed to be attached by the coupling thread only. Omni-
directional, self supported directly into the pipework. Use a 19mm AF (3/4") spanner on the
hexagon provided to apply a maximum torque of 15.8Nm. The Customer must ensure that the
pressure seal is suitable for the application. If in doubt contact Gems Sensors.
ELECTRICAL INSTALLATION
All types with the CE Mark include suppression devices providing transient protection to
EN 61326-4 and EN 61326-2-3. Conformity with the requirements of the CE mark only applies
when connection is made with Gems Sensors approved cable, see APPROVED CABLE section,
and is connected as shown below:-
Millivolt Output Transducers: Four core screened cable should be used with the cable screen
connected to the instrumentation earth. The cable screen should not be connected to the
transducer body.
High Output Transducers/Transmitters: The screen of the cable must be earthed at the
instrumentation end. If an 'Earth Loop' problem is encountered when the body of the unit is
earthed by the pipework it is permissible to remove the cable screen from the instrumentation
earth.
APPROVED CABLE
Gems sensors uses cables comprising 2, 3 or 4 colour-coded cores, enclosed by an aluminised
polyester screen where the screen is in intimate contact with a separate drain wire. The outer
sheath is chrome PVC and overall diameter is approximately 4 mm.

OPERATION
Having installed the transducers as instructed, they are ready for use. The transducer should not
be removed whilst the system is at pressure.Before applying power, check that the correct
polarity and excitation levels are being applied. See Table 1 for electrical connections.
CALIBRATION
Transducers are calibrated to the datum requested at time of order; this can be identified by the
sixth letter of the identification code as follows:-
A- Absolute datum
G- Gauge datum vented to atmosphere via the electrical connector or cable
LOAD CHARACTERISTICS (4-20mA Current Output)
The total resistive load in the loop (to include all the cable resistance) can be from 'zero to
50 x (supply volts -7) ohms' e.g. with a 24V d.c. supply the permissible load is from zero up to
850 ohms.
OPERATIONAL LIFE:
Limited to 100M cycles to maximum allowable pressure.
WARRANTY
We guarantee this instrument against faulty workmanship and material for a period of one year
from date of delivery. The Company undertake to repair, free of charge, ex-works any
instrument found to be defective within the specified period providing the instrument has been
used within the specification in accordance with these instructions and has not been misused in
any way.
Detailed notice of such defects and satisfactory proof thereof must be given to the Company
immediately after the discovery and the goods are to be returned free of charge to the Company,
carefully packed and accompanied by a detailed failure report. See "RETURN TO FACTORY".
WETTED PARTS
316 and 17-4 PH stainless steel plus Nickel Braze to BS1845 : NK3/HTN2.
