With its industry standard process connections the OPTIBARPM3050 is universally used for general purpose pressure applications with analog 2-wire output and digital HART® communication. The transmitter features a compact stainless steel housing, easy setup options, superb accuracy and rapid response times as well as long term stability.

These features are made possible by using sensors which are extremely stable across a wide range of temperatures and pressure conditions. Additional digital compensation reduces the temperature dependence on the pressure measurement.

A variety of front flush and hygienic process connections with 3A / EHEDG approval are provided in addtion to standard threaded and flanged connections as well as diaphragm seal assembly with OPTIBAR DSP series.

The measuring cell itself is a fully welded stainless steel construction (1.4435 / 316L). Especially for small measuring ranges, high overload factors ensure that the pressure transmitter is resistanant to pressure spikes.

The protection category IP66/67 (NEMA 4X) or IP66/68 (NEMA 4X/6P) depends on the selection of the electrical cable gland.

Internally located push buttons make it possible to easily set the offset correction, zero point and measuring range for quick start-up. Alternatively, an optional LCD display enables simple and intuitive setup of all configuration parameters via 4 push buttons.
