Multirange pressure transmitters

August 2010 Pressure Measurement & Control

Within the Jumo range, ASSTech Instrumentation offers low cost pressure and differential pressure transmitters suitable for measuring partial vacuum and differential pressure in non-corrosive gas applications.

Type 402004 is applicable in HVAC, clean room engineering and filter monitoring applications. Measuring ranges can be set by DIP switches: 0-250, 0-500, 0-1500 and 0-3000 Pa. Outputs are switch able 0-10 V or 0(4)-20 mA. Electromagnetic compatibility is to EN 61326-1 with interface emission to Class B and interference immunity to industrial requirements. The transmitters can withstand mechanical shock 10 g/0,1 sec and vibration to a maximum 5 g at 15-2000 Hz.

The ABS enclosure offers protection to IP54. Process connection supplied is 6,6 mm and electrical connection is via internal screw terminals for conductor cross-sections up to 1,5 square millimetres.
