Our facilities now include the capability, with three separate test machines, plus dead weights to offer UKAS traceable calibration in tension and compression from 5N to 1800kN.

We offer either a UKAS traceable calibration service or the equipment may be hired for customers wishing to carry out their own calibrations.

The DS200 covers ranges from 0-100mbar up to 0-600 bar with either a 4-20mA or 0-10Vdc output, with an overall accuracy of 0.25% of full scale.  There are many options for both pressure connection and for electrical connection, with plug and socket (IP65) or cable (IP67) exits available.

The display has 4 digit resolution with rotation on 2 axes, offering 240º on the front face and 300º from the transducer housing, thus enabling adjustment to its optimum viewing position.

The unit comes standard with one set point with a second set point optional, each set point is freely configurable from 0% to 100% of full scale.  All DS200 transducers utilise a Stainless Steel diaphragm, ensuring compatibility with a wide range of process media and excellent long-term stability.

NOTE:  The DS200 is no longer a current product so this article exists for reference only.  It has been replaced by the Pi600DD Pressure Sensor with Digital Display.

Specifically designed for the measurement of cable tension and under hook crane and lifting gear weighing, the complete ET Telemetry Lift Link system consists of a robust telemetry load cell with an internal data transmitter with a range of 200 metres, together with a portable handheld receiver instrument, displaying the weight digitally.

The ET telemetry load cell is available in ten different ranges from 0-1 to 0-500 tonnes and offers excellent performance with a repeatability of <0.05% of rated output.  It has been designed for use with standard lifting shackles and is sealed to IP66 for waterproofing to withstand arduous outside conditions.

The ET lift link telemetry load cell’s weight and height have been kept to a minimum, thereby reducing the overall headroom required for the installed system.  The portable instrument receives the load cell transmitted signal at typically 420MHz and displays the weigh value on the 8 character 14 segment LCD display, over the range of -4999 to 65000.  Features on the unit include a ‘hold’ control for display storage, and a ‘tare’ control for automatic zeroing of the load signal.  It operates on a 9V PP3 supply, with auto power down to conserve battery life.

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.

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).
