Description

Series AT-MS ATEX/IECEx Approved Magnesense® Differential Pressure Transmitter, Series

MS in Flame-Proof ATEX/IECEx Enclosure

 

The DWYER Series AT-MS Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity in hazardous areas. This DWYER Series AT-MS Differential Pressure Transmitter is loaded with features such as: field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal and the ability to select a square root output for use with pitot tubes and other similar flow sensors. Along with these features, the magnetic sensing technology provides exceptional long term performance and enables the Magnesense® transmitter to be the solution for a myriad of pressure and flow applications. Flameproof enclosures are available in aluminum and can include a glass window for viewing process on the LCD.

 

Important notes for installation:

  • Cables must be fitted through 1/2″ NPT cable gland or ATEX/IECEx conduit (not supplied with instrument).
  • Make sure after cabling to close tight cover and cable gland, in order to maintain IP66 rating.
  • Open cover only after de-energizing instrument.

 

Product Applications

  • Monitor pressures in ducts, rooms, or total building pressures
  • Filter monitoring
  • Local indication of clean room pressures with process signal sent to control room
  • Hazardous area pressure measurement and transmitter

 

Features

  • All the capabilities and value of the MS2 in an ATEX/IECEx approved enclosure
  • Long service life and minimized downtime due to durable, rugged housing and high-quality components
  • High impact strength and high temperature rated for applications where hazardous environments exist
  • Increased response time at low pressures with LD port configuration
