Description
The Modus W30 is a wet/wet differential pressure transmitter for liquids and gases, using two piezoresistive sensors whose difference is calculated electronically, so the unit cannot be damaged if one side loses pressure. Ranges run from 0–6 psid (50 kPa) to 0–200 psid (1,500 kPa) with ±0.5% accuracy and line pressures up to 100 or 300 psi.
Only welded 316 stainless steel touches the process, it gives a two-wire 4–20 mA output from 11–32 V DC, and it is housed in an IP65 die-cast aluminium enclosure with zero and span adjustment.
Argonmark Ltd supplies Modus instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
