The Pirani measurement signal is for switching the HIMS on and off, thus protecting the HIMS from burning or excessive contamination. -
Page 16: Bayard-Alpert Measurement System
Product description tion area between P and P is the pressure area in which the gauge proportionally uses both the upper lower Pirani measurement system and the HIMS to determine the pressure. The Pirani proportion decreases as the pressure decreases. In the "hard" switch position, the switchover between Pirani and HIMS is immediate, without a transition. -
