Overview","Designed specifically for 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 and dynamic response and resistance to side load. The Subminiature Gauging DVRT® feature sub-micron resolution, linear analog output, flat dynamic response to kHz levels, and very low temperature coefficients. Extremely lightweight, captive cores are small and rugged. Manufactured using corrosion-resistant alloys, Subminiature Gauging DVRT® are suitable for short term submersion in harsh media such as brake fluid and hot saline.","Sensor Design","Core position is detected by measuring the coils’ differential reluctance using a sine wave excitation and synchronous demodulator. This differential detection method provides a very sensitive measure of core position while cancelling out temperature effects.","The transducers’ coils and Teflon® cables 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 short term immersion in saline and pressurized oil.","Units available for long term immersion, corrosive and high pressure environments can be custom built to meet such requirements. LORD MicroStrain®’s desktop consoles and in-line signal conditioners provide the Subminiature Gauging DVRT® with plug and play housing, power, analog output, LCD display, RS-232 output and software. A range of modular positioning attachments and custom strokes are also available.","Features and Benefits","High Performance","Ease of Use
