Product Description

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.
 

Product Features

 

• 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

Applications

• 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
