Adopts a unique special Pirani gauge! A Pirani vacuum gauge equipped with two relay contacts.
The "Pirani vacuum gauge" is a thermal conductivity type vacuum gauge that utilizes the change in electrical resistance of a heated filament in a vacuum, which varies with pressure. The 'PG-3F2/PG-4F2' is a model equipped with two relay contacts, based on the 'PG-3F/PG-4F'. Since the meter and the main unit (amplifier) are integrated, it is compact and inexpensive, and the inclusion of relay contacts makes it suitable for various control applications. It is suitable for pressure measurement in rough vacuum systems of all types of vacuum equipment and is frequently used, serving as a key component in automatic devices. Additionally, improvements can be made according to customer requests. 【Features】 ■ A model equipped with two relay contacts based on G-3F/PG-4F ■ Compact and inexpensive, suitable for various control applications ■ Minimal changes over long periods of continuous use ■ Utilizes a unique special Pirani bulb for stable operation and reliable measurement values ■ Easy to handle, allowing for wide and convenient vacuum level measurement *For more details, please refer to the PDF document or feel free to contact us.
