CP30

Conductivity Probe

Description

The Spirax Sarco CP30 conductivity probe is used in conjunction

with a controller to measure the conductivity (or TDS) of water,

usually in a steam boiler for the purpose of monitoring and

controlling blowdown.

The probe may be installed in a Spirax Sarco probe elbow, a

screwed flange, or directly in a boiler connection. The CP30 is

supplied in four nominal tip lengths, and is cut to the exact length

required prior to installation.

A DIN 43650 cable socket with Pg 11 cable gland is supplied with

the unit.

Principal features:

-

Conductivity probe for use with blowdown controllers.

-

Suitable for use in steam boilers up to 32 bar g, 239°C.

-

All wetted parts in austenitic stainless steel /PTFE.

-

Easily cut to length.

Approvals:

The CP30 is also available with a 1⁄2" NPT screwed connection,

approved to UL61010. Please note that this version will not

be marked and is not suitable for Europe.

Caution:

The probe is not suitable for outside installation without

additional environmental protection.

Available tip lengths mm (inches)

300 (11.8), 500 (19.7), 1 000 (39.4) and 1 500 (59).
