The PMP71B is a member of the new generation of Cerabar transmitters. The transmitter is robust and uses a secure Bluetooth connection; using a mobile device and installing an app, the instrument can be controlled remotely.
The software is very simple to use. The intuitive operating wizard guides the user step by step through instrument setup, functional safety tests and verification tests.
Heartbeat Technology provides self-verification and self-monitoring functions that can detect process anomalies such as changes in loop parameters.
Advantages
Heartbeat Technology lets you verify the health of the instrument without interrupting the production process.
The instrument status is clearly indicated: as soon as a diagnostic message appears, the display switches from green to red
Reduced risk of system failure, error-free SIL commissioning and guided instrument functional safety tests
Use the SmartBlue App to wirelessly and remotely control devices in the production area
Application areas
Maximum applicable pressure: 700 bar (10500 psi)
Maximum temperature of instruments with diaphragm seal systems: 400°C (752 °F)
Maximum measuring accuracy: +/- 0.025%
