Low Range Differential Pressure Transmitters Measure Down to 25 Pascals

Thursday, May 1st, 2003

pr3200-200x200Applied Measurements have launched their PR Series of differential pressure transmitters, specifically designed for the measurement of differential pressure at very low ranges down to 25 pascals (0.25mbar) covered by the PR3202 model, and operation at high static pressures up to 300 bar on the PR3200 model.  All three models cover a wide range of applications and come fully temperature compensated ensuring high levels of stability.

All of the PR series differential pressure transmitter models have a standard 2 wire, 4-20mA output and are robustly built to withstand the arduous conditions of process and industrial environments.

The PR3202 low range differential pressure transmitter covers ultra low measurements from 0-25 pascals up to 0-1000 mbar (0-100kPa) and is housed in an RFI shielded, wall mounted box.  Zero and span controls are easily accessible for on-site calibration and adjustment.

The PR3200 is designed for wet/wet differential pressure measurement from 0-250mbar up to 0-200 bar and the IP65 enclosure allows the units to be easily mounted using an angle bracket.

pr3202-200x200For heavy duty operation, the PR9200 differential pressure transmitter has ranges from 0-1.2mbar up to 0-65bar with static pressure operation up to 300 bar.  It has environmental protection to IP67 and intrinsically safe versions are available for use in hazardous areas.

All PR differential pressure sensor models are ideally suited to flow measurement applications using Pitot tubes, orifice plates and mass flow meters as well as combustion chamber control and clean room monitoring applications.

Applied Measurements are leading specialists in pressure and force measurement and are pleased to discuss your specific application.

Miniature LVDT Displacement Sensor for OEM Applications

Thursday, May 1st, 2003

mini_lvdtApplied Measurements’ new miniature LVDT displacement sensors have been designed to meet the needs of OEM applications making them suitable for use in load and pressure measurement, weighing equipment and closed loop control systems.

The sensors use the well-proven LVDT technology with its advantages of no wearing parts together with reliable and accurate performance in a variety of operating conditions.

The AML/M series of miniature LVDTs are available in measuring ranges from ±0.25mm up to ±75mm with a choice of mechanical attachments including core only, core and extension, plus sprung-loaded with ball end.  The low mass of the core offers particular advantages in projects where minimal weight restrictions apply.

All miniature LVDTs are calibrated to an accuracy of 0.5% of stroke length and will operate over a standard temperature range of -30ºC to +85ºC, with an option to extend this to +150ºC.  They are fitted with robust screened cable which can be supplied in a 4 or 6 wire format.

To create a complete displacement measurement or control system, Applied Measurements also offer a comprehensive range of analogue amplifiers and digital displays to suit a variety of engineering applications.

Compact Under-Hook/Lifting Gear Telemetry Load Cell & Display

Thursday, May 1st, 2003

et-telemetry-200x200The latest weighing system from Applied Measurements Ltd is one of the first of its kind to use a telemetry link between the load cell and the portable digital display instrument, thus eliminating the problems associated with a long interconnecting cable.

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.
