Gemco 955A BRIK Gen III

The 955A BRIK Gen III is an accurate programmable, auto-tuning, non-contact, linear displacement transducer in an economical, low proﬁ le package. The transducer utilizes our ﬁ eld proven magnetostrictive technology to give absolute position, repeatable to .006% of the programmable sensing distance.

The streamlined anodized aluminum extrusion houses the sensing element and electronics. The magnet moves over the sensing element that determines the position and converts it to an analog output. It can be ordered with a 0 to 10 VDC or 4 to 20mA output.

The 955A BRIK Gen III has a few truly unique features. The ﬁ rst one is the LDT’s auto-tuning capability, the ability to sense a magnet other than the standard slide magnet and adjust its signal strength accordingly. Another feature is the analog output is programmable over the entire active stroke length. The active stroke area of the LDT lies between the Null and Dead zones. There is a diagnostic LED located at the connector end of the probe that remains green while a good magnet signal is present and when the magnet is in the programmed stroke area. The LED turns yellow when the magnet is out of the programmed active range, but still within the active stroke area. The LED turns red and the output goes to 0 volts on voltage output units, or 4mA on current output

units when there is no magnet present or when the magnet is out of the sensing area.

The unit can easily be changed in the ﬁ eld from a 0 - 10 VDC to a 10 - 0 VDC or 4 - 20mA to a

20 - 4mA . As an added feature, the optional differential analog output allows the distance between two magnets to be measured.

The 955A BRIK is designed for applications where economical continuous feedback is necessary. The sensor can be a cost effective replacement to limit switches, proximity sensors, linear potentiometers and LVDT’s. Applications include presses, blow molding, injection molding, extrusion, roll positioning, dancer control and many more.
