Brand: Spirax Sarco
Product Code: SPIRAX-LP21-1050
Quantity:

Spirax LP21 Level Probe
1050mm Long Tip
PA420 Pre-Amplifier Sold Separately

Description The Spirax Sarco LP21 is a capacitance probe designed for modulating level control in conductive liquids, in conjunction with a PA420 preamplifier, which is supplied separately. It can also be used for adjustable on/off control.

The LP21 may be used with one or more controllers or transmitters to provide level control, level alarms, and/or outputs to a building management system.

The probe is normally installed in a steam boiler or metal tank where it is earthed through the ½" BSP screwed connection, the boiler or tank forming the earth return path.

It may be used in a non-conductive tank (e.g. plastic or concrete) if an earth rod is provided.

The PA420 preamplifier (described in separate literature), is screwed to the top of the probe and hand tightened, enabling easy removal without the need to disturb the probe.

Caution: 
The probe is not suitable for outside installation without additional environmental protection.
