* Transducer should not be subjected to greater than the maximum allowable pressure or
temperature as defined in the transducer specification.
* 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 wetted parts which are stainless
steel to UNS 31803, Ceramic and Nitrile
* Exposed end of cable must be kept free from moisture.
* Liquid must not be allowed to freeze in the pressure port.

MECHANICAL INSTALLATION
Pressure Connections:
1) G¼ internal pressure connection to BS2779. Alternative fitted as specified at time of
order.
2) KF25 Flange
Pressure couplings screwed into G¼ pressure ports should have a maximum thread engagement
of 13 mm and UNDER NO CIRCUMSTANCES be allowed to touch the pressure sensitive
diaphragm. Pressure couplings should be sealed against the outer face at the pressure port entry
using bonded seal washer such as:-
Part Number Description
234646-0002 G¼ bonded seal up to +100°C operation.
Dowty Ref: 400-021-4490-02
499207-0002 G¼ bonded seal up to +200°C operation.
Dowty Ref: 300-021-0967-02
499207-0006 G1/8 bonded seal up to +200°C operation.
Dowty Ref: 300-020-0967-02
Refer to Dowty for external pressure ratings.
Mounting: Pressure Transducer is designed to be attached by the coupling thread. Alternatively
units fitted with an immersible cable can be suspended via the cable or flange. Omni-directional.
To fit, use a M16 (5/8 UNF) AF spanner on the hexagon provided and apply maximum torque of
27 Nm (20 lbf-ft). The Customer must ensure that the pressure seal is suitable for the application.
