The model 736.51 capsule pressure gauge is based upon the proven capsule measuring system and is suitable for very low pressures. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.

For the version with switch contact, magnetic snap-action contacts, reed switches, and electronic contacts are available. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used.
