Ametek Gemco 953D-VP VMAX Linear Displacement Transducer - RS422 Variable Pulse (PWM) Output (Special Order)
Rugged Linear Displacement Transducer (LDT) in a rod-style package. RS-422 variable pulse (PWM) digital output. Uses Ametek's field proven magnetostrictive technology to give absolute position, accurate to .01% of the programmable sensing distance.
The 953D-VP is an accurate and rugged 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 953D-VP variable pulse system, or pulse width modulated (PWM), generates a digital output over a RS-422 line. The system is available with both internal and external interrogation. The system with external interrogation looks for a recommended one microsecond input pulse, or start pulse, which is provided by the customer’s computer device. An output pulse is then generated by the LDT with a duration proportional to the position of the magnet. Using the internal interrogation option, the output signal will be generated automatically without an input pulse. For both internal and external interrogation, the frequency of the signal generation is dependent upon settings made at the factory. Recirculation from one to 127 are available through these factory settings.
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.
