The pressure gauges are supplied in various sizes and models. In addition to the standard connections other connections are available upon request. The gauges are provided with dials according to EN 837-1 and are available in the following ranges: Suction pressure: -1/+12 Bar with temperature scale. Discharge pressure: -1/+30 Bar with temperature scale. Oil pressure: -1/12 Bar of –1/+30 Bar without temperature schale. The ammonia gauges are provided with an R717 temperature scale, for the freon gauges the following temperature scales are standard: As single temperature scale: R22 R134A R404A R407C R507 As triple temperature scale: R134A/R404A/R407C R22/R134A/R404A R22/R404A/R407C R22/R404A/R507 R75 A75 DR75 DA75

Ammonia pressure gauge, suction, discharge or oil pressure, diameter 63/100/160mm

Combined suction/discharge pressure gauge for freon installations, diameter 100mm. Available with or without back flange.

Combined suction/discharge pressure gauge for ammonia installations, diameter 100mm. Available with or without back flange

Models and Connections:

The R376 and A376 gauges are differential pressure gauges whereby the static pressure as well as the differential pressure can be read at a glance. Available in a range from –1/+12 Bar or –1/+30 Bar with a differential pressure of standard 0/+6 Bar. Available with a diameter of 100mm, with or without back flange and various connections. For minimum and maximum pressure signalling the PC160R and PC160A contact pressure gauges can be used. The gauges have a diameter of 160mm and are provided with a back flange as standard. The PC160R and PC160A have electronic built-on contacts, while the PC 160R/DH and PC160A/DH are provided with electronic built-in contacts.
