Gas Measuring Systems
Particle Monitoring Systems

Fixed Detectors

Our fixed Gas Measuring Systems provide gas monitoring options for Oxygen, Carbon Monoxide, Carbon Dioxide and a range of toxic gases. They offer trusted and comprehensive protection for public, personnel and plant.

Gas Measuring Systems incorporate a range of sensing technologies including infrared, electrochemical and solid state gas sensors, depending upon the gas chosen. As our sensors are also utilised in our own Gas Measuring Systems and monitors, you can choose from our selection of add-ons and accessories to provide a complete monitoring solution when required.

Tech details

Housing is aluminium, IP54 and suitable for wall mounting. Basic processing and output of the measured values (4-20mA linear output) are integrated into each measuring system. Evaluation and further processing of the measured values occur in downstream devices selected by the user, for example, ventilation systems, limit monitors, display or programmable logic controllers.

Where required, Euro-Gas offers MODBUS cards to convert the 4-20mA signals from the Gas Measuring Systems into digital signals. This digital signal can be transferred via a serial RS485 interface to a central computer, which can be located up to 1,000 metres away (see MODBUS card part nos. 2112B1050/2112B1055).

Alternatively, choose from our Limit Monitors/Gas Detection Controllers, which are programmable, self-monitoring and equipped with a rolling, alphanumeric display. They evaluate the signal measured by the Measuring Systems to which they are connected, (for example: toxic or explosive gases; Oxygen, Carbon Monoxide, Carbon Dioxide, etc.). When the values exceed or fall below a defined limit value, they emit an alarm or trigger other downstream functions, such as ventilation, in two stages. Two to six different measuring systems can be connected to one Limit Monitor via 4-20mA interfaces. Thus, one Limit Monitor can monitor different types of gases simultaneously (see part nos. 2112BGWZ-S2/-S4/-S6).

A test and calibration gas cap is available to fit all Gas Measuring Systems. This allows for ease of connection with customer’s tubing for gas test and calibration (see part no. 2112B1010).
