Rheonik RHE21 Coriolis Transmitter

Measures mass, density, volume and temperature.
Colour changing display depending on measurement status.
Set can be password protected.

The RHE21 is an extreme application transmitter available with 316 stainless steel corrosion resistant housing. The enclosure is also IP66/NEMA7X as standard and can be changed to IP67.

Process

A variety of units are available to measure mass flow, volume, density and temperature. There are ports for up to 2 digital controllable inputs and one analogue 4-20mA active input.

The display is a back lit LCD display that will change colour if the system believes there are faults with the measuring instruments. When installed, the set up and calibration of the RHE21 become password protected to prevent unwanted changes.

Output options

Output options include 2 analogue 4-20mA outputs that have a 0.1% uncertainty of the reading. Two digital status outputs and two pulse /frequency outputs are available.

The transmitter comes with ports for 2 digital inputs and for one 4-20 mA active analogue input. Communications are via MODBUS RTU and a USB connection to a PC with RHECom software.

Size and weight

Dimensions vary depending on construction time but are approximately 255x200x100mm. The weight of the transmitter is 8kg.

There is an integral sensor cable that can be either 3 or 10m long. An optional IS terminal is available for other length cables.
