Differential Pressure Switch D02 Delta Mobrey

Based on the success of the “Industrial” range of process control instrumentation, Delta Mobrey 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 repeat ability 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.

The Sentry Series offers exceptional performance and high build quality in a simple, safe and cost-effective package.

  • Performance is assured by repackaging Delta’s well proven sensor technologies in a new, simple, one-piece
  • Safety is maintained by a vent that prevents the enclosure becoming pressurized in the event of a sensor
    being damaged.
  • Cost is minimised through the selection of common standard options although, as with all Delta products, a
    variety of optional extras are available to tailor the product to specific needs.
