1: Introduction
1.3 System Overview
The key element of the TX-KFP is an electrochemical gas sensor. Nearly all types operate
according to the principle of membrane electrolysis. See appendix 2 for an explanation of the
membrane electrolysis principle.
The TX-KFP operates on 24-Volt DC, usually supplied by an alarm/control unit.
The signal coming from the gas sensor is converted into a 4-20mA signal and transferred
through the 2 wire shielded cable to the alarm/control unit.
Signal transmission can take place over distances up to 1000 meters.
The industry standard KF40 vacuum type flange connection allows for quick and easy
installation.
Fig.1.3.1 gives an overview of some possible configurations.
1.4 Identification of Bionics systems and components
Bionics Instrument uses a Toxic Gas (TG) number to identify a gas or group of gases. This
number is a ‘100’ number. For example; Ammonia is TG-2400.
For a full list of the TG codes please refer to our documentation.
The Gas Sensor (GS) number has been derived from the TG number. This means the GS
number for a specific gas or group of gases will start with the same ‘100’ number. For
example; the GS-2460DP is a sensor for the detection of ammonia. The GS number is followed
by a code identifying the type of sensor.
Accordingly a TX-KFP for use with a GS-2460DP gas sensor is identified by:
TX-[2460]KFP
BP
- exchangeable electrochemical sensor
DP - refillable electrochemical sensor
EP - exchangeable electrochemical sensor
ELP - exchangeable electrochemical sensor
MP - exchangeable electrochemical sensor
