Rixen Messtechnik

Rixen Messtechnik designs and manufactures mechanical differential pressure instruments based on the Ringbalance measuring principle. Made in Germany since 1955, Rixen Messtechnik instruments are used where very low differential pressure needs to be measured reliably, clearly and consistently.

Able Instruments are Rixen Messtechnik’s Exclusive Representative for Sales and Service in the UK and Ireland, supporting customers with application review, range selection, configuration and after-sales support.

Rixen Messtechnik Ringbalance instrument manufacturing and assembly

A specialist manufacturer of Ringbalance differential pressure instruments

Rixen Messtechnik specialise in low differential pressure measurement for industrial, process, HVAC, cleanroom, furnace, biogas and hazardous-area applications. Their instruments are designed around a mechanical Ringbalance measuring principle, allowing very small pressure differences to be displayed locally and, on selected models, converted into transmitter or control signals.

The Rixen Messtechnik range includes local indicators, analogue and digital transmitters, a differential pressure controller and an intrinsically safe ATEX version for hazardous-area use. This makes the range suitable for customers who need more than a standard electronic pressure sensor, especially where local readability, stable mechanical measurement and application-specific configuration are important.

The Ringbalance measuring principle

Rixen Messtechnik Ringbalance instruments use a mechanical measuring principle for very low differential pressures. Instead of relying on springs or diaphragms, the measurement is based on the movement of a partially filled ring body, a calibration weight and fixed geometry. Rixen’s new website explains this principle in detail, including how pressure differences are converted into rotation and then into a readable indication.

This approach is particularly relevant where small pressure spans need to be measured clearly and repeatedly. Rixen Messtechnik’s current product information highlights measurement from 40 Pa, long-term mechanical stability and the ability to configure ranges to suit the application. The mechanical display can operate without auxiliary power on local indicator versions, while transmitter and controller models provide signal outputs where integration with external systems is required.

Applications for Rixen Messtechnik instruments

Rixen Messtechnik instruments are used across applications where low pressure, draft or differential pressure is important to process safety, product quality or energy efficiency. Typical applications include cleanroom pressure cascades, HVAC and filter monitoring, ventilation systems, furnace and combustion pressure control, biogas plant pressure monitoring and hazardous-area differential pressure measurement.

In these applications, the buyer often needs to balance several requirements: local visual indication, remote signal transmission, control functionality, hazardous-area approval, measuring range, scaling, overload protection and installation conditions. The Rixen Messtechnik range provides different instrument types for these different requirements, rather than forcing all applications into one standard transmitter format.

Rixen Messtechnik products from Able Instruments

Able Instruments supply and support the core Rixen Messtechnik Ringbalance differential pressure range in the UK and Ireland. The range includes the RW65 analogue differential pressure indicator, MU-Digital LCD differential pressure transmitter, MU-Analog-65 analogue display transmitter, Rixotact_4 differential pressure controller and RW65_EX_II intrinsically safe ATEX differential pressure gauge.

Each product is configured around the application. Depending on the model, this may include measuring range, scale unit, output signal, supply voltage, housing material, limit contact options, overload protection and hazardous-area requirements. Able Instruments can help review these requirements before quotation to reduce specification risk.
