描述
HAWK 61L and 61B series capsule system pressure gauges are designed to measure low pressure from 6 inH2O to 15 PSI. These use a diaphragm capsule as its sensing element. The sensing element consists two half capsules which are soldered together. The diaphragm capsule element expands by subjecting to pressure. The expansion is converted into the rotary motion of the pointer by a movement. This motion makes users read the scale easily. The wetted parts can be in beryllium copper or brass.
