Rheonik RHE26 Coriolis Transmitter

Digital data is communicated via Modbus RTU on RS485. Data can also be transmitted through a USB connection to a PC running Rheonik RHEcom software.

Configurable output types to measure mass, density, volume and temperature.
Modbus RTU connection to control systems.
Colour LCD display with lockable front protector.

The RHE26 is a multifunction transmitter that provides a variety of measurements. Mass flow, density, volumetric flow and temperature are all able to be measured and can be displayed with a choice of units.

Pressure and temperature pctflow RHE26 Coriolis Transmitter

The transmitter can be mounted via a rack, panel or DIN rail. It is compatible with every RHM sensor and can be used in combination with a sensor that is in a hazardous zone. The RHE26 has ATEX/IECEx approval for use in ordinary locations.

About Thyristor pctflow RHE26 Coriolis Transmitter

Two pulse/frequency outputs are available as is an analogue 4-20mA output. A configurable digital input can be used for zeroing and measurement holding.

The back lit display gives a change of colour depending on the health of the flow meter and subsequent accuracy of the measurements. An optional, lockable cover can be used to protect the display. The lockable cover provides the front screen with IP54 protection but as standard the RHE26 is protection class IP20.

Features for Rheonik RHE26 Coriolis Transmitter

Multifunction Measurement: Provides real-time data for mass flow, volumetric flow, density, and temperature.
Assurance Factor® Diagnostics: Includes an advanced diagnostic suite that monitors sensor health and process conditions. The backlit LCD changes color (e.g., turns red on error) to provide immediate visual feedback.
Batch & Filling Control: Features an integrated batch controller with self-learning capabilities for precise dosing and filling applications.
Flexible Mounting: Designed to fit standard IEC 61554 panel cutouts or can be mounted on a DIN rail.
Connectivity: * USB Port: Located on the front for easy configuration via RHECom software.
- RS485/Modbus RTU: For seamless integration into PLC and SCADA systems.
Hazardous Area Compatibility: While the transmitter is typically installed in a safe area, it is designed to interface with Rheonik RHM sensors located in Zone 0, 1, or 2 (ATEX/IECEx approved).
