It aims at general applications in the Beverage Industry, water & wastewater, iron & steel, OEM/ Automation and other process industries.
Typical applications include absolute and gauge pressure measurement of gases, vapours and liquids, hydrostatic level measurement in open tanks, pressure monitoring in pipelines, dry-run protection of pumps or compressor monitoring.
OPTIBAR PM 3050 is a cost efficient device fitting between KROHNEs ultra compact pressure transmitters and the high-end process series OPTIBAR 5060. It features a robust and fully welded stainless steel design with a metallic diaphragm and is available with a variety of (hygienic) front flush or recessed threaded and flange process connections starting at DN25/ 1″. Available approvals include 3A, FDA, EHEDG, EG 1935/2004 and ATEX / IECEx Ex ia.
OPTIBAR PM 3050 can be used for process temperatures up to -40…150°C / -40…302°F without additional diaphragm seal. For aggressive media and/or higher temperatures, it can be combined with OPTIBAR DSP series diaphragm seal assemblies, providing a wide range of special materials as well as a temperature decoupling up to 400°C / 752°F.
The measuring range reaches from 0.1…100 bar / 1.45…1450 psi, with a smallest measuring range of 100mbar / 1.45 psi and a measuring accuracy up to ±0.1% of set span. It offers high overload factors especially for small measuring ranges, and a quick step response time < 80 ms.
Internally located push buttons allow for easily setting the offset correction, zero point and measuring range for a quick start-up. Alternatively, an optional LCD display offers convenient commissioning and setup of all configuration parameters via 4 push buttons. The 2-wire device comes with 4…20 mA output and HART 7.5 communication.
