Ametek Gemco 953S VMAX Linear Displacement Transducer - RS422 SSI Digital Output (Special Order)
Rugged Linear Displacement Transducer (LDT) in a rod-style package. RS-422 Synchronous Serial Interface (SSI) digital output. Uses Ametek's field proven magnetostrictive technology to give absolute position, accurate to .01% of the programmable sensing distance.
The 953S is an accurate and rugged SSI digital output Linear Displacement Transducer (LDT) in a rod-style package. This transducer uses Ametek's field proven magnetostrictive technology to give absolute position, accurate to .01% of the programmable sensing distance. It has a wide power range of 7 to 30VDC @ 1 watt. The Ametek 953 series has an auto tuning feature that allows it to sense a magnet other than the standard ring magnet and adjust its signal strength accordingly.
The 953SSI VMAX provides an RS-422 Serial Synchronous Interface (SSI) output signal that is proportional to the position of the magnet assembly along the length of the probe. The displacement value is encoded into a 24, 25 or 26 Bit format and can be transmitted at high speeds.
The unit can be ordered in span lengths from 1" to 300" in .1" increments. For lengths over 72", please contact us. On unsupported stroke lengths greater than 4 feet, rod support bracket(s) and a special magnet should be used.
A complete system normally requires the following components:
- 953 transducer
- Magnet (purchased separately)
- Cable Assembly (purchased separately)
- Mounting brackets / hardware. (purchased separately)
Usually ships 8-10 weeks after receipt of order
Gemco linear displacement transducers are built to order, and are not returnable. If you have any questions about using this product in your application, please do not hesitate to call or email us.
