Miniature displacement sensors - DVRTs, include gauging, non-gauging (free sliding core) and non-contact displacement transducers.
The product line includes sub-miniature displacement sensors, micro-miniature displacement sensors, and miniature non-contact displacement sensors.
The Subminiature Gauging DVRT delivers high performance in a small package. Designed to get into tight spaces while providing an exceptionally smooth static & dynamic response, and resistance to side loading.
Description
Designed to get into tight spaces, the subminiature gauging DVRT delivers high performance in a small package. A ruby bearing and hardened stainless steel ball guide the spring loaded tip, providing an exceptionally smooth static & dynamic response, and resistance to side loading.
Features of submini-gauging DVRT's include: micron to submicron resolution, linear analog output, flat dynamic response to kHz levels, and low temperature coefficients. Extremely lightweight, captive cores are small yet rugged. Corrosion resistant alloys allow complete submersion of the instrument.
Multichannel signal conditioners are provided as "plug and play" enclosures, w/ keyed cables & UL approved supplies. Miniature circuit cards are also available for high volume OEM customers. As with all MicroStrain products, every device is carefully tested prior to shipment, and calibration data are included with each order.
How it works
Core position is detected by measuring the coils' differential reluctance, using a sinewave excitation and synchronous demodulator. This differential detection method provides a very sensitive measure of core position, while cancelling out temperature effects.
The transducer's coils & multistranded leads are sealed in vacuum pumped epoxy, within the stainless steel case. This provides outstanding environmental resistance. The DVRT® has been successfully employed in harsh applications, including immersion in saline and pressurized oil.
