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 use in Zone 1 Hazardous Areas, 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 screwed lid and integral terminal block which provides quick and easy access for commissioning 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.
