Pressure work in the field often exposes instruments to wet conditions, changing locations and fast test routines. This waterproof handheld family gives technicians a flexible pressure meter for mobile use with GMSD ... - K51 and MSD pressure sensors, covering ranges from -1.999 ... 2.500 mbar relative up to 0 ... 1000 bar absolute.
The devices adapt to different pressure tasks through selectable units such as mbar, bar, Pa, kPa, MPa, mmHg, inHg, PSI and mH2O. Depending on the connected sensor and model, they measure relative, absolute and differential pressure, with 4 / s or 1000 / s measuring frequency for static checks or fast pressure changes.
An illuminated 4 1/2 digit display, min/max memory, hold function and freely adjustable user unit support clear readings on site. Selected models add data logging, dP/dt, pitot-based air velocity and volumetric flow calculation, alarm functions and a scalable 0-1V analog output. The IP65/IP67 housing and 2*AAA battery operation support mobile use outside the cabinet.
The family works with GMSD ... - K51 pressure sensors and MSD sensors with MSD-K51 connection cable. Sensors connect through a 7-pole bayonet connector.
The devices support relative, absolute and differential pressure measurement, depending on the connected sensor and device configuration.
GMH 5155 provides two sensor inputs and can display or record sensor 1, sensor 2 and the calculated difference sensor 1 - sensor 2.
The display unit depends on the connected sensor and includes mbar, bar, Pa, kPa, MPa, mmHg, inHg, PSI and mH2O. A freely adjustable user unit is also available.
Users can select slow measuring at 4 / s, fast filtered measuring at 1000 / s or peak detection at 1000 / s.
GMH 5150 and GMH 5155 support manual recording with measuring point input and automatic recording with selectable cycle time from 0:01 to 60:00.
The output can be used for the USB 5100 serial interface. GMH 5150 and GMH 5155 also provide a scalable 0-1V analog output.
GMH 5150 and GMH 5155 provide calculated display values for pressure change per time, pitot-based air velocity and volumetric flow.
