How to specify TDS conductivity probes shall be Spirax Sarco type CP42 with nickel alloy sensor tips and built-in temperature sensor. They must incorporate a patented facility to check the sensor tips for scaling. When used in conjunction with an appropriate Spirax Sarco controller, they must also be able to automatically initiate a patented probe cleaning feature, which, if unable to clean the probe, will activate a warning on the controllers display panel and/or a remote alarm. The system must also be able to automatically compensate for any polarisation effects at the sensors. They must be suitable for boiler pressures up to 32 bar g and a maximum working temperature of 239 ° C. They must be available in 300 mm, 500 mm and 1 000 mm lengths, and have a " BSPT boiler connection.
How to order Example: 1 off Spirax Sarco CP42, twin tip conductivity probe having a ½ " BSP connection and 300 mm tip length.
