The HPM188 is an all-stainless steel, explosion-proof pressure transmitter featuring a high-precision silicon sensor. It converts pressure into standard current or voltage signals for seamless integration with control systems. Built for durability, it offers excellent shock resistance and long-term stability in hazardous environments.
- Compact and Lightweight Design: These products offer strong flameproof performance while maintaining a small size, light weight, and aesthetic appearance, ideal for space-constrained installations.
- Durable Stainless Steel Construction: The transmitter is built from stainless steel, ensuring strong corrosion resistance and a high protection grade (up to IP67), allowing for continuous use in harsh conditions.
- High Precision and Stability: Featuring a stable and reliable silicon piezoresistive chip, the device uses temperature compensation to maintain high accuracy and offers good long-term stability, reducing maintenance needs.
- Reliable and Responsive Circuitry: An integrated, high-reliability circuit ensures quick response times and was specially developed for standard 4~20mA pressure transmitters, facilitating easy connection to control instruments.
