Client Warranty
Prior to installation, the equipment referred to in this manual must be stored
in a clean, dry environment, in accordance with the Company's published
specification. Periodic checks must be made on the equipment's condition.
In the event of a failure under warranty, the following documentation must be
provided as substantiation:
1. A listing evidencing process operation and alarm logs at time of failure.
2. Copies of operating and maintenance records relating to the alleged faulty
unit.
Use of Instructions
Although Warning hazards are related to personal injury, and Caution hazards
are associated with equipment or property damage, it must be understood that
operation of damaged equipment could, under certain operational conditions,
result in degraded process system performance leading to personal injury or
death. Therefore, comply fully with all Warning and Caution notices.
Information in this manual is intended only to assist our customers in the efficient
operation of our equipment. Use of this manual for any other purpose is
specifically prohibited and its contents are not to be reproduced in full or part

To ensure that our products are safe and without risk to health, the following
points must be noted:
1. The relevant sections of these instructions must be read carefully before
proceeding.
2. Warning labels on containers and packages must be observed.
3. Installation, operation, maintenance and servicing must only be carried out
by suitably trained personnel and in accordance with the information
given.
4. Normal safety precautions must be taken to avoid the possibility of an
accident occurring when operating in conditions of high pressure and/or
temperature.
5. Chemicals must be stored away from heat, protected from temperature
extremes and powders kept dry. Normal safe handling procedures must be
used.
6. When disposing of chemicals ensure that no two chemicals are mixed.
Safety advice concerning the use of the equipment described in this manual
or any relevant hazard data sheets (where applicable) may be obtained from

1 INTRODUCTION
Information.
• Pressure range must be compatible with the maximum pressure being
measured.
• Pressure media must be compatible with the transmitter wetted parts
listed in these instructions.
• Liquid must not be allowed to freeze in the pressure port.
• Exposed ends of cables must be free from moisture.
• The gasket must be fitted under the electrical connector.
• Wetted parts:
17 – 4 PH stainless steel plus Nickle Braze to BS1845 : NK3/HTN2.
The Series 2000 Pressure Sensors are ideal for applications where a
conventional transmitter is too expensive and over specified. The Series 2000 is
a low-cost simple transducer which can be used in a large number of applications
ranging from heating and ventilation to industrial hydraulics
Series 2000 sensors can be used as a primary sensor, utilizing one of ABB’s
control products, e.g. COMMANDER 300/310 etc.
3 ELECTRICAL INSTALLATION
3.1 Electrical Connections
See Table 3.1 for electrical connections.
Electrical Connections +ve –ve case earth
Pin 1 Pin 2 Pin 4
Electrical Specifications Rated Min/Max. Milliamps
24V d.c. 12 to 36 4 to 20
3.2 Grounding
All versions should be grounded by the installation pipework. If this is not possible,
the sensor should be grounded at the instrumentation end via the appropriate pin
or green lead. For maximum protection against RFI all versions should be installed
using screened cable with the screen grounded at the instrumentation end.
3.3 Resistive Loading
The total permissible resistive load in the loop (to include all the cable resistance)
can be from ‘zero to 50 x (supply volts –12) ohms, eg. with a 24V d.c. supply the
permissible load is from zero up to 600 ohms, see Fig. 6.1.

3.4 Applying Power
Before applying power, ensure the correct polarity and excitation levels are
applied.
3.5 Calibration
Transmitters are calibrated to a fixed range at time of order,identified by the fifth
and sixth letter of the identification code marked on the sensor housing
– see
Specification Sheet SS/2000.
4 MAINTENANCE
4.1 Routine Inspection
Limited to periodic inspection of the cable and connector to ensure that these are
neither damaged nor softened by incompatible liquid.
4.2 Repair
The instruments cannot be repaired locally. If damaged, return to the Company at
the address shown overleaf or to accredited dealers when a
replacement/repair is required.
2 MECHANICAL INSTALLATION
2.1 Pressure Connections
• Gl/4 external to BS 2779 compatible with ISO 228 (recommended seal
Part Number 232646-0002 or Dowty Part Number 400-021-4490-41).
2.2 Environmental Limits
• Temperature limits: –20°C to 80°C.
