Introduction Features & Benefi ts
Designed to get into tight spaces, the sub-miniature 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.Features of the sub-miniature DVRT’s include: sub-micron resolution, linear analog output, fl at dynamic response to kHz levels, and very low temperature coeffi cients. Extremely lightweight, captive cores are small yet rugged. Manufactured using corrosion-resistant alloys, the sub-miniature gauging DVRTs are suitable for submersion in harsh media such as brake fl uid and hot saline.Miniature “plug and play”
signal conditioners provide linear DC output when supplied with unregulated DC power. Multi-
channel, OEM and digital display systems are also available.Custom ranges are available on request. • available with sub-micron resolution and long stroke range• operating temperature to 175 °C
