1. Better than 1% set-point repeatability
   Users can expect a set-point repeatability performance better than 1% on all configurations with some configurations being significantly better
2. Extensive range of options
   The Performance Series switches are available with an extensive range of materials, process connections, switch types, electrical entries, etc and offer customers many millions of different possible configurations.
3. More than 35 years experience in the field
   Installed in a wide range of applications from nuclear power plants to offshore oil rigs, the Performance Series’ long experience in the field offers customers the reassurance that they can be relied upon to survive the test of time in the harshest environments.

Designed in the mid-1970s and developed over subsequent years, the Performance Series switch range offers users the broadest range of options, the highest levels of set-point repeatability and the confidence of long term performance that a mature product such as this can prove.

The model 771 Performance Series Vapour Pressure Temperature Switches comprise an armoured capillary attached to the sensing bulb via a semi-rigid extension on which a compression gland slides to enable various depths of thermowell (pocket) to be accomodated. This sensor is coupled to the microswitch via a precision stainless steel mechanism, the combination of which helps deliver the market leading performance customers can expect from the Series.

• Ranges available up to 150°C
• Weatherproof IP66 enclosures in zinc alloy or stainless steel
• ATEX and IECEx Ex d Flameproof models available
• Environmentally and Hermetically sealed switch options
• Set-point adjustable over the full range against a calibrated scale with tamperproof adjuster

1. Hinged lid
   A unique hinged lid gives users access to the contact terminals and set-point adjuster quickly and simply via a single captive screw
2. Better than 1% set-point repeatability
   Users can expect a set-point repeatability performance better than 1% on all configurations with some configurations being significantly better
3. 5 year warranty
   A market leading 5 year warranty gives users peace of mind
4. Safety
   All Sentry models come with a safety vent to prevent the enclosure becoming pressurized in the event that the sensor is inadvertently damaged by excessive pressure. In addition, the complete Sentry family has been assessed for use in SIL 2 safety related systems.

Based on the success of the “Industrial” range of process control instrumentation, Delta Controls has developed the “Sentry” range of Pressure, Differential Pressure and Temperature Switches.

Designed for general purpose use in OEM equipment and industrial power applications alike, Sentry combines economy, quality and performance.

With a better than 1% set-point repeatability and a market leading 5 year warranty, Sentry offers real value.

Users also benefit from a unique hinged lid and single captive screw which provides quick and easy access to terminals and set-point adjustment. The inclusion of a safety vent also protects users by preventing the enclosure becoming pressurised in the event that the sensor is inadvertently damaged by excessive pressure.
