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

February 1st, 2001

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.

NOTE: March 2010 – The P9911 is no longer a current product so this article exists for reference only.  The P9911 has been replaced by our Pi9911 Re-Rangeable Depth Sensor.

TR200 Portable Battery-Powered Strain Gauge Digital Indicator Launched

February 1st, 2001

tr200-200x2001Applied Measurements are introducing their model TR200 portable battery powered strain gauge digital indicator. This compact instrument is designed to read outputs from load cells, pressure transducers and most other strain gauge sensors with a full bridge configuration and output sensitivity between 0.75mV/V and 7.5mV/V.  Bridge resistances as low as 85 ohms are compatible with the TR200.

This versatile instrument which is sealed to IP65, making it ideally suited to a wide range of applications in the automotive, process control, water, aerospace and marine offshore industries where short term measurements are required.  The TR200 is particularly suited to on board vehicle datalogging.

All adjustments are entered via the sealed key pad to enable the user to set zero, scaling, decimal points, least significant digit blanking, filtering, calibration checking and peak hold.   Once the parameters are set, all the menu keys can be disabled to ensure keys are not pressed by mistake.  The instrument can remember the parameters of up to 10 different sensors and all values are retained in EEPROM for permanent storage.

The instrument is fitted with a sealed rechargeable lead acid battery which provides an operational period of at least 35 hours when connected to a 350 ohm bridge and a separate charger is supplied for recharging.

Further factory fitted options are available to expand the capabilities of the TR200 providing RS232 communications, data logging, printer interfacing, analogue retransmission and trip outputs.  A facility also exists within the TR200 to externally switch channels either via a separate switch box or through intelligent plugs fitted to any sensor plugged into the TR200.

As an added feature, the instrument can be supplied fully calibrated with any strain gauge sensor complete with certification traceable to UKAS (NAMAS as was).
