Description

WIKA capsule pressure gauge model 612.20.100 is designed for stable indication of very low pressures and vacuum using a proven capsule measuring system where capsule expansion is transmitted to the movement and displayed on the dial. It is intended for gaseous, dry and non aggressive media and is commonly used in medical, vacuum, environmental and laboratory duties as well as contents measurement and filter monitoring. The instrument is built with a stainless steel case and bayonet bezel for durable everyday service, while the process connection is made from copper alloy and supplied as a G 1/2 B BSPP Thread bottom mount for standard installation. This configuration provides a clear NS 100 dial with a -150 to 150 mbar vacuum and pressure scale, front zero point correction for quick setting during commissioning, IP54 ingress protection, EN 837-3 design marking and accuracy class 1.6 for dependable local indication.

Applications

  • Draft and chimney pressure monitoring in boilers, heaters and flues
  • Filter and blower differential pressure indication at very low pressures
  • Sensitive low-pressure pneumatic control and monitoring
  • Laboratory and environmental monitoring of ultra-low gas pressures
