Sensor Chambers and Sensors

Spiratec sensor chamber description

The Spiratec trap fault detection system is designed to operate on

saturated steam systems only, to indicate whether a steam trap is

leaking steam. When combined with the R1C or R16C automatic

trap monitor and WLS1 waterlogging sensor assembly, it will

detect if a steam trap has failed closed or is blocked.

As standard - The sensor chamber has the sensor connection

on the right hand side of the chamber when viewed from the

direction of flow. If required - Chambers can be supplied with

the sensor connections on the left hand side 'L', but must be

requested when placing an order, i.e. 1⁄2" ST141L.

Spiratec sensor description

Spiratec sensors are designed to fit into Spiratec sensor chambers

as part of the Spiratec trap fault detection system.

Available types:

SS1 standard sensor: For the detection of steam leaks when

used in conjunction with a sensor chamber and a Type 30 or

Type 40 hand held indicator, R1C or R16C automatic trap monitor.

SS1's are normally supplied already fitted into the sensor chamber.

WLS1 waterlogging sensor assembly: For the detection of

steam leaks or traps that have failed closed or are blocked when

used in conjunction with an R1C or R16C automatic trap monitor.

WLS1's are normally supplied as separate items for fitting into a

sensor chamber on site.

Note: sensor chambers without sensors are available from stock.

A sensor blanking plug is available at extra cost, to protect the

external connection of the SS1 standard sensor chamber from dirt.

connections

The SS1 standard sensor is threaded 2" parallel BSP for assembly into the Spiratec sensor chamber. An external

SS1

screw thread (M22 x 1.5) is provided to allow permanent installation using the PT2 or PT3 connector. Three

standard types of connector are available for use with the SS1 standard sensor:

Waterlogging sensor assembly is supplied complete with 1 m of high temperature three core cable for connection to

an R1C automatic trap monitor. It can also be connected to an R16C automatic trap monitor using a special diode pack.
