PTB110 Barometer for Industrial UseThe Vaisala BAROCAP ® Barometer PTB110 offers outstanding long-term stability.Features/Benefits▪▪▪▪▪▪▪▪▪Vaisala BAROCAP® sensorSeveral pressure rangesAccuracy ±0.3 hPa at +20 °CLong-term stabilityOn/off control with externaltriggerOutput voltage 0 ... 2.5 or0 ... 5 VDCCurrent consumption less than4 mAMountable on a (35 mm wide)DIN railNIST traceable (certificateincluded)PTB110The Vaisala BAROCAP ® BarometerPTB110 is designed both for accuratebarometric pressure measurementsat a room temperature and forgeneral environmental pressuremonitoring over a wide temperaturerange.Vaisala BAROCAP®technologyThe PTB110 barometer uses theVaisala BAROCAP ® Sensor, a siliconcapacitive absolute pressure sensordeveloped by Vaisala for barometricpressure measurement applications.The sensor combines the outstandingelasticity characteristics andmechanical stability of single-crystalsilicon with the proven capacitivedetection principle.Accuracy and stabilityThe excellent long-term stability ofthe barometer minimizes or evenremoves the need for field adjustmentin many applications.ApplicationsThe PTB110 is suitable for a variety ofapplications, such as environmentalpressure monitoring, data buoys,laser interferometers, and inagriculture and hydrology.The compact PTB110 is especiallyideal for data logger applications as ithas low power consumption. Also anexternal On/Off control is available.This is practical when the supply ofelectricity is limited.
