ANALOGPIRANI & PENNING GAUGES The dhve Pirani gauge is a pressure control instrument designed with the thermal conductivity type gauge head (Sensor). This provides all necessary bridge circuits and signal conditioned analog outputs. This instrument works on the principal of change in resistance of material with a change in temperature. This can be used to measure vacuum from Atmosphere to 0.001 m.bar , anywhere in the vacuum system with a suitable adopter. His gauge is very much essential in the pirani controller vacuum (0.5 m.bar to 0.001 m.bar). Two gauge heads can be directly connected to this gauge to read fore vacuum and roughing vacuum of a vacuum system. PENNING The dhve Penning gauge is a pressure control instrument designed with the cold cathode type gauge head (Sensor). This provides all necessary circuit and signal conditioned analog output. This gauge cover a pressure range of 1 x 10-3 to 1 x 10-6 m.bar with instant range change. No manual adjustment is required and pressure is indicated in a clear front Display directly calibrated in m.bar. Categories: Measuring Instruments, Vacuum Gauages.
