SmartDPT Dewpoint Transmitter -120 to + 20 ° C dew point temperature

An advanced dew point transmitter

The SmartDPT makes monitoring dew points as easy as measuring temperature or pressure and can be immediately integrated into air or gas measurement and control systems. The highly automated manufacturing, calibration and test processes make the SmartDPT not only a very robust and reliable, but also a very inexpensive measuring instrument. By using our replacement sensor program, users can be sure that their process moisture measurement system will never be interrupted.

CombiSens multi-parameter platform for gas analysis

Multiparameter controller for analog and digital transmitters with extensive analyzer functions for Industry 4.0 - integration into a large number of fieldbus systems!


You are looking for a gas analyzer that can determine several parameters of a gas or gas mixture. Cross-sensitivities or physical and chemical restrictions force you to discard various measuring principles. This results in a colorful mix of products from different manufacturers. That means that you have many devices, high space requirements, different operating concepts of the devices, many passwords and finally the time-consuming integration into your control with various interfaces that do not optimally fit your infrastructure.

We have developed a universal controller that is unique on the market. It combines the functions of a multi-parameter gas analyzer with the possibility of integrating almost any measuring principle and this completely independent of the manufacturer!


CombiSens multi-parameter platform

The new generation of gas detectors: SD-3 series

The products of the SD-3 series are stationary explosion-proof gas detectors that can continuously monitor the surrounding atmosphere for flammable gases, toxic gases and oxygen. These detectors detect gas leaks and trigger an alarm if preset concentrations are exceeded. The detected gas concentration is converted and output in the form of a 4 - 20 mA analog output and a digital HART output signal. Other output options include Modbus communication (RS-485) and the use of three relays.

The robust housing construction (housing material: stainless steel, protection class corresponds to IP66/67) allows use in a wide temperature range from -40 to +70 °C (varies depending on sensor specification). A number of different mounting types (e.g. wall, pole and duct mounting) support a wide range of applications and installation environments.

The SD-3 series products also include the newly developed "F Sensor" sensor series. These high-performance smart sensors offer significantly improved performance compared to previous sensors, with a sensor degradation and lifetime evaluation feature and a three-year warranty.

Gas detectors from RIKEN KEIKI for Li-Ion battery production | Battery cell production

You supply the accumulators, we supply the gas detectors for safety in your production!

Lithium Ion Battery FactoryVariety of solvents are added to electrolytes, such as DMC, EMC and DEC. These have the potential to explode when vaporized, so gas detectors are required.
Silikon reduziert Sensor sensitivitySensors contaminated with silicon cannot provide correct readings because the response to NMP is compromised. In addition, RIKEN has taken measures to significantly reduce the sensor's loss of sensitivity.

In the manufacture of lithium-ion batteries, there are a number of points to consider with regard to safety in production.

  1. Explosion protection (vapours from solvents and electrolytes)
  2. Toxic gases endanger the health of employees
  3. Aspiration of hazardous dusts (graphite, lithium cobalt dioxide)

RIKEN KEIKI offers NMP monitoring for battery cell production. N-methyl-2-pyrrolidone is used in the production of lithium-ion batteries and is toxic and also highly flammable.

For flammable and toxic gases that can be released during filling, coating and drying, the SD series from RIKEN KEIKI offers excellent solutions, even at temperatures up to 200°C.

Stationary (e.g. SD-3) and protable devices such as e.g. the GX-6000.
