The OPTIBAR PM 3050 is a compact pressure transmitter with recessed diaphragm for general purpose pressure and level applications. It is designed for gauge or absolute pressure measurement of air, inert gases, steam and clean liquids in pipes, tanks or reservoirs. It can also be used for cost-effective hydrostatic level measurement of clean liquids in open tanks. A wide range of hygienic process connections with front flush diaphragm compliant with 3-A sanitary standard and EHEDG hygienic design places the OPTIBAR PM 3050 perfectly in food and beverage pressure and level applications.
The pressure transmitter has an excellent measuring accuracy over a wide temperature and pressure range. It also features very short response times (<50 ms), outstanding repeatability and very good long term stability. Additional digital compensation reduces the temperature dependence on the pressure measurement. The electronics and the optional display and adjustment module are located in a rugged fully welded stainless steel housing. For a quick commissioning, the zero point and measuring range can be easily adjusted via internal push-buttons.
Highlights:
Fully welded stainless steel construction
The fully welded stainless steel construction provides utmost robustness and sturdiness which are as important as accurate and precise measurement.
High accuracy and temperature stability
The full digital linearization and temperature compensation provides an accurate measurement signal under changing temperature conditions.
OPTIBAR DS series diaphragm seals
Some applications require extended temperature decoupling or special wetted materials for corrosion, adhesion or abrasion protection. An OPTIBAR DS series diaphragm seal provides here an optimal solution, which is carefully sized and fully welded for long lasting performance.
Display and adjustment module
Local indication of the measurement value as well as an easy and effortless configuration of the device are two significant benefits of an integrated display and adjustment module. The module can be placed on any device of the same series.
Increased temperature limits
The sensor has been designed to withstand process temperatures up to +300°C / +572°F.
High overload resistance
Pressure spikes have an extensive effect on the measurement accuracy and physical integrity of the measuring cell. A robust pressure sensor provides high factors between the nominal range to fulfill the basic requirements of the measurement task and an maximum working pressure, which limits the maximum allowable pressure without permanent drift or damage.
