PISTON TYPE MECHANICAL DIFFERENTIAL PRESSURE GAUGE
Fillable
REOTEMP’s Series D20 Piston Type Mechanical Differential Pressure Gauges are primarily designed for liquid applications. Differential pressure is sensed by the movement of a precisely ground floating piston/magnet in a precision bore against a calibrated spring. A rotary pointer magnet located close to the internal magnet follows the movement of the piston magnet and indicates differential pressure on the dial. Piston type differential pressure gauges exhibit a slight amount of bypass as the fluid crosses from the high to the low pressure port.
