The Spirax Sarco LP30 level probe is used with a Spirax Sarco LC3050 level controller to provide a high integrity, self-monitoring low level alarm signal, usually in a steam boiler. It consists of a probe body with a removable cable socket, and a separate screw-on probe tip which is retained by a lock-nut and pin. The probe has a level sensing tip (probe tip), and a comparator tip. The earth return path is via the body connection.
Under normal operating conditions the probe tip is partially immersed, and the resistance to earth is low. When the water level drops below the probe tip the resistance to earth becomes high, causing the controller to give a low level alarm signal. The comparator tip compensates for any leakage to earth caused by scale, dirt, or internal moisture, ensuring a low water alarm signal even under adverse conditions.

High integrity self-monitoring low level alarm probes, Spirax Sarco type LP30 with austenitic stainless steel bodies and probe tips, PTFE probe sleeving, and cable socket with Pg 11 cable gland. They must have a comparator tip to compensate for scaling, and a positively located probe tip. They must be used with an appropriate Spirax Sarco controller.
