Gas detectors E2606 are intended for air quality monitoring - control of combustible gas and oxygen concentration and prevention of gas leaks in confined spaces.
Depending on version the gas detector E2606 uses either advanced metal-oxide semiconductor or an electrochemical gas sensor. Concentration of combustible (methane, butane,hydrogen, etc) gases can be measured.
- Temperature range -20..+50 °C, <90 %RH
- Output relay 230V, 3A
- Supply 230 VAC or 24 VDC
- Diffusion, flow-through and remote sensor versions
- Visual and audible alarms, adjustable output relay
- Linearized analog output 4-20 mA
- RS485 Modbus RTU interface option for direct Fieldbus networking
- Wall-mount

The gas measuring systems for explosive gases and vapors made by J. Dittrich Elektronic determine the concentration of explosive gases and vapors in air in an ambient temperature from -10 to +50° C.
A pellistor or semiconductor sensor detects methane (CH4), hydrogen (H2), propane (C3H8), alcohol and benzine; additional hydrocarbons on request.
The calibration is carried out with the aid of the respective test gas by means of a potentiometer; however, a certain amount of cross-sensitivity of the sensor with regard to the other substances always remains.
Low-cost infrared measuring system for methane
Since the cross-sensitivity of the sensors gives rise to problems when monitoring methane, J. Dittrich Elektronic developed a new infrared measuring system which detects specifically methane quicker, more accurately and at less cost than conventional infrared systems.

Transmitter - AST 3IS
AST 3IS
* Unique design to allow transducers in hazardous areas without the need of zener barriers
* Analogue output ± 10 VDC, 0-20 or 4-20 mA
* Seriel communications: RS-485, MODBUS RTU protocol
* Relay outputs
* Compact DIN rail mounting
* CE compliant - EMC and Low Voltage
The unit AST 3IS is a DIN rail mounted, high performance isolation amplifier designed for applications with strain gauge transducers inside hazardous areas.
AST 3IS has at its heart a unique Nobel patented analogue to digital converter. The unit is equiped with analogue as well as digital outputs which can be conditioned to give the user accurate, stable and fast response measurement information.
The transmitter is fitted with two relay outputs having a short response time for use in high precision level control applications.
The AST 3IS is compatible with other instruments in the Vishay Nobel programme and can communicate via the RS-485/MODBUS RTU protocol with a common process control host - PC/PLC. Fieldbus communication is possible via the GATE 3S module from Vishay Nobel.
* [EEx ia] IIC approved
* Excellent performance in spite of EX version
* Fully isolated
* Simple earting (compared with zener barriers)
* Direct connection of transducers in hazardous areas without the need af zener bariers
