1. INTRODUCTION

SensePoint is for the detection of toxic gases and is

designed for use with an approved junction box.

It employs an electrochemical cell sensor device which is

gas specic and used as part of a 4-20mA loop powered

measuring circuit. The sensor includes a voltage clamp

within a sealed Exd enclosure and an electrochemical cell

driver and cell within an IS portion of the sensor.

Different sensor versions detect different gases. Sensors

are available for the detection of H

S, CO, CI

, NH

, H

, SO

NO, NO

, O

. The sensor is available in M20* or 3/4 NPT

thread versions. All accept accessories from the specied

range. Should you require information outside the scope of

these instructions please contact Honeywell Analytics Ltd.

This product is certied for use in hazardous areas and is

protected against water and dust ingress to IP65, or IP66/67

if approved weather protection is tted.

*NOTE - M20 thread option awaiting certication.

This product complies with the relevant CE standards

concerning performance: EMC to BS EN50081 parts 1 & 2,

BS EN50082 parts 1 & 2 and EN 45544.

Exd

Flame proof or explosion proof within the connes of European

standards EN50014 and EN50018. An enclosure that can

withstand the pressure developed during the internal explosion

of an explosive mixture and which prevents transmission of

the explosion to the explosive atmosphere surrounding the

enclosure.

Exe

Increased safety within the connes of European standards

EN50014 and EN50019 applied to electrical apparatus that

does not produce arcs or sparks in normal service, in which

additional measures are applied so as to give increased

security against the possibility of excessive temperatures.

PPS

Polymer polyphenylene sulphide, suitable for use in most

chemical environments (eg acids, aldehydes, ketones,

alkalies, petroleum, aromatic hydrocarbons, alcohols, ethers,

esters and most chlorinated hydrocarbons). Avoid immersion

in solvents for extended periods. For further details contact

Honeywell Analytics Ltd.

Intrinsically safe, apparatus in which the circuits themselves

are incapable of causing ignition of a ammable gas.
