Robust 5:1 Turndown Level Transmitter Measures Up To 100m Depth

Applied Measurements’ P9911 series submersible depth sensor is available in ranges from 0-2 to 0-100 metres water gauge and provides an industry standard 4-20mA output. The all stainless steel sensor offers great flexibility, with its two piece body design providing ease of access to the zero and span potentiometers and 5 to 1 turn down switches, allowing full field adjustability.

The two halves of the unit are bolted together using six Allen screws and sealed by means of an ‘O’ ring.  This, together with an IP68 sealed polythene cable outlet, completes the high integrity waterproof assembly which maintains full sealing to a depth of 100 metres.

Both the sensor and electronics are protected against the effects of lightning strikes offering distinct advantages over competitive products.

The P9911 is fully temperature compensated and is ideal for long term bore hole monitoring.

Options include extended temperature ranges and alternative body materials for chemical and seawater applications.
