TRANSMITTERS

GNW Ltd Manufacture, Repair and Calibrate an extensive range of Transmitters used in all types of control fields, offering reliability and accuracy even under the most severe conditions.

GNW Transmitters measure the process variables:- * Temperature * Pressure * Absolute pressure * Differential pressure * Flow * Level

and convert these into standardised electrical signals which can then be applied to analogue and digital controllers, process control systems or recording and indicating units.

GNW Transmitter series offer unmatched versatility and a wide range capability.
Some applications in which are transmitters are used are:
* Engineering,
* Power,
* Iron,
* Steel,
* Paper
* Food

Your choices are infinite and are limited only by your application.

Our manufacturing procedures assure robust construction and a long maintenance free life. Offering a range of transmitters to a high standard of excellence which is both competitive and guaranteed to satisfy your requirements.

GNW’s transmitters are manufactured in stainless steel or corrosion resistant materials to meet even the most severe application. Contained in water tight housing the electronic module is permanently sealed from moisture and contamination for a long life even in chemical environments.

Each transmitter offers a wide range of inputs that can be configured to transmit your input signal with incredible accuracy in any engineered units desired.

STANDARD PRESSURE TRANSMITTERS The GNW series Pressure Transmitters have been designed to meet the requirements of the majority of industrial applications of pressure measurement requiring an output signal of 4-20mA Robustly constructed from stainless steel this range of pressure transmitters incorporates the latest technology in ceramic thick film pressure sensing offering excellent stability and accuracy over a long service life

Typical applications for GNW’s standard pressure transmitters include machine tools,
mechanical and civil engineering installations, process plant, production test facilities, water resources and power generation.

STANDARD PRESSURE TRANSMITTERS DIN RAIL MOUNTABLE GNW’s range of Pressure transmitters incorporates the highly stable ceramic Pressure Diaphragm with a unique high performance amplifier to give excellent reliability over a long service life. DIN rail or bulkhead mountable the complete assembly is protected to IP65.

TWO WIRE DIFFERENTIAL PRESSURE TRANSMITTER The GNW series Pressure Transmitters have been designed to meet the requirements of the majority of industrial applications of pressure measurement requiring an output signal of 4-20mA Robustly constructed from stainless steel this range of pressure transmitters incorporates the latest technology in ceramic thick film pressure sensing offering excellent stability and accuracy over a long service life

DEPTH & LEVEL TRANSMITTERS GNW’s range of Depth and Level Transmitters have been designed for the accurate measurement of depth in fluids compatible with stainless steel and alumina. The ceramic measuring diaphragm is an insulator with a bridge of high resistance thus greatly reducing the problem of strain gauge burn out from high voltage surges, experienced in field applications.

Electrical connection is via a screened cable protected by a tough nylon pressure tight sheath which allows excellent trouble-free venting to the surface. It is important that the top end of the sheath is terminated into a protected dry area to prevent any condensation occurring.
Standard depth transmitters are fitted with nylon nose cones to prevent sludge build-up. For measurement of depth in sludge/slurry materials the transmitters are mounted on a platform to lift the diaphragm of the
transmitter above the sludge/tar level.

Typical applications include reservoir levels, borehole fluid levels, water mains pressure inspection chambers, power level, outlet pressure on submersible pumps and slurry/sludge level measurement.

PRESSURE TRANSMITTER WITH BARRIER SEALS GNW offer a range of barrier seals for applications where the process media is unsuitable for direct contact with the transducer diaphragm. Seals are available in a variety of forms and materials for particular purposes. They may be directly attached to the process connection or remotely via capillary.
