The HPM730 is a rugged pressure transmitter built for extreme industrial applications, especially where fluids are thick, gritty, or prone to clogging. Its cavity-free, flat film diaphragm is its standout feature, ensuring it won't get blocked by mud, cement, crude oil, or slurries. Combined with strong vibration resistance, high-temperature capability, and overall robust design, it's engineered to deliver accurate pressure measurements reliably in harsh and hostile environments.
- High-accuracy foil strain gauge
- Measuring diaphragm without cavity
- Wear resistance
- Wide operation temperature range
- Optimal circuit and structure design, vibration resistance and high stability
- Food and medicine equipment pressure testing
- Environmentally friendly chemical coatings, polyurethane equipment
- Mud, coal slurry, pulp, crude oil, asphalt, etc.
- Oil field drilling, well logging, logging, offshore oil production, etc.
- Industrial sites that require anti-blocking, high-intensity vibration and impact
