1: Introduction

1.1 Instrument Overview

The TX-KFP series are highly reliable stand-alone systems capable of detecting a wide variety

of toxic, corrosive and flammable gases both in low parts per million (ppm) concentrations as

well as in the higher concentrations (vol. %).

The key element of the system is an electrochemical sensor which has been designed for a

highly selective response to a specific gas or group of gases.

The gas detector models TX-KFP are diffusion type systems designed for use as

environmental gas detection system or as in-line gas detection system for exhaust systems.

The sensor is capable to operate under high humidity conditions and may be used as a stand-

alone system or linked to an optional control system.

The industry standard KF40 vacuum type flange connection allows for quick and easy

installation.

Features:

An electrochemical gas sensor, maintainable for almost all types

24 V DC operated / 4 - 20 mA output

Local display of gas concentration (analogue or digital indication)

Test and calibration with ‘live gas’ in safe concentrations

A good zero stability and high sensitivity.

Calibration both on- and off-site

Easy mounting by means of industry standard KF-connection

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

Other identification codes used in this manual:

PC- Printed Circuit board

RX- Alarm/Control Unit

A- Analogue Display

D- Digital Display

EL- Electrolyte

M- Membrane
