 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
 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
 5 year warranty
A market leading 5 year warranty gives users peace of mind
 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.

Robust weatherproof, epoxy coated, aluminium housing approved to IP66 and NEMA 4X
SPDT and DPDT switch contacts with environmentally and hermetically sealed options
Stainless steel wetted parts as standard
Better than 1% set-point repeatability
Market leading 5 year warranty
Pressure ranges from 0.4 to 700 bar (4 to 1500 psi)
Pmax up to 1000 bar depending on range
