Mantracourt’s PSD, a portable strain gauge display for use as a strain-gauge indicator or load-cell indicator, is now used by engineers around the world in a broad range of industrial applications.

Enabled for automatic sensor calibration and having a waterproof enclosure, long battery life and sister handheld for RS232 output, the PSD strain gauge indicator is suitable for a broad range of industrial applications where load, pressure, force or weight measurement data needs to be reliably and accurately recorded.

Having been developed over recent years for use in harsh environments, the PSD is also small and light, making it suitable for the collection of strain gauge and load cell data in industrial and architectural environments.

According to Mantracourt, it has sold many thousands worldwide and it expects similar growth in sales over the next few years.

A typical application of the PSD digital display has been the monitoring of the loads on guide wires, used to maintain the stability of radio masts.

Load shackles with built-in TEDS capabilities are used in the guylines.

The TEDS shackles have the intelligence to hold the calibration details of the associated shackle.

Using a TEDS-enabled PSD load-cell display, an operative can connect the PSD to each shackle through a five-pin Binder socket and the mating connector supplied.

Once connected, the load can be easily read by the PSD using the simple peak/valley hold or gross/net keyboard functions.

As calibration is not required, the handheld does not need to be informed as to what shackle it is currently measuring.

This prevents mix-ups occurring when taking readings.

Anyone attending the mast can simply take the readings required by connecting and switching on the PSD.

Alternatively, using the PSD232, the sister of the PSD, connection to RS232 can be made that will allow users to interface with a PC or datalogger, for example.

The PSD232 sends the displayed value to the RS232 port at 9600 baud in an ASCII format, terminated by a carriage return and line-feed.

Weighing 250g, the battery-powered device is easy to carry and also waterproof to IP65 standard.

It has a seven-digit LCD display, with battery, peak, trough, net, overload and shunt cal indication.

It also features a tactile keyboard, with on/off, range select, peak/valley hold, and gross/net controls.

Being microprocessor-based, it allows for a single-pass calibration facility (direct mV/V).
