A capsule gauge uses a sealed capsule (two corrugated diaphragm halves welded together) as the sensing element. When pressure enters the capsule, it expands axially, moving a lever arm connected to the pointer. Capsule gauges are far more sensitive than Bourdon tubes — standard ranges start at 0.5 mbar — making them the correct choice for gas pressure, duct pressure, and draft measurement.
With the standard capsule: reliable measurement from 0–1 kPa (10 mbar). With the high-sensitivity capsule option: 0–0.5 mbar — resolving individual Pascal changes. Below 0.5 mbar, a manometer (liquid column) or electronic differential pressure transducer is more appropriate.
ZX-07 is designed for gases and clean air. The capsule material is 316L SS (standard) or brass. Not suitable for liquids, condensing vapours, or sticky/viscous gases that would coat the capsule interior. For liquid or aggressive vapour service, use the diaphragm gauge ZX-05.
The single-capsule version measures gauge pressure (relative to atmosphere). A dual-capsule DP version is available for measuring pressure differences between two gas streams (e.g. filter DP across an air-handling unit). Specify DP range and connection arrangement at order.
G1/4B (standard) or G1/8B (miniature). For duct pressure tapping, the gauge connects via a 6 mm or 1/4" OD tube nipple inserted through the duct wall with a rubber grommet seal.
Class 1.6 (±1.6% FS) standard. On a 60 kPa scale, that is ±0.96 kPa. For very-low-range capsules (0–1 kPa), Class 1.6 represents ±16 Pa — adequate for duct balance work. For higher precision (±5 Pa), specify an electronic differential pressure transmitter.
The capsule deflection at full scale is smaller than a Bourdon tube, so the movement amplification ratio must be higher to drive the pointer to full scale. This requires a longer pointer and, consequently, a larger dial. ZX-07 typically uses a 100 mm or 150 mm dial for ranges below 10 kPa.
The capsule deflects onto a protective stop at approximately 150–200% FS, preventing permanent deformation. Sustained overpressure above 200% FS will distort the capsule — replace, do not recalibrate. Unlike a Bourdon tube, a distorted capsule shows a visible deformation on inspection.
Standard ZX-07 is IP54. For outdoor or wash-down service, specify the IP65 hermetically sealed case. Ensure the process connection is protected from direct water ingress, which would enter the capsule and freeze or corrode.
A manometer uses a liquid column (water or mercury) to indicate pressure — accurate but fragile, position-sensitive, and requires manual reading. ZX-07 uses a mechanical capsule with a pointer, is portable and position-insensitive, and reads directly in kPa or mbar. For pressures above ~10 mbar, ZX-07 is more practical for field use.
