Overview

The HPM720 Tri-Clamp Sanitary Pressure Transmitter is a specialized pressure measurement solution designed for hygienic industrial applications, featuring a 1.5''/2'' tri-clamp flat diaphragm design and optional customized cooling fins for high-temperature media. Engineered with a silicon pressure core as the sensitive element, it uses food-grade silicone or olive oil as pressure transmission media, ensuring compliance with strict hygienic standards for food, pharmaceutical and medical industries. Constructed entirely from 316L stainless steel, this transmitter is corrosion-resistant, vibration-resistant and compact, with extensive temperature compensation for stable performance in dynamic industrial processes. Its exposed flush diaphragm at the chuck end eliminates scaling, blockages and dead volume—common pain points in viscous fluid measurement—while supporting both gauge pressure (-100kPa~0~10kPa~2.5MPa) and absolute pressure (0~20kPa~2.5MPa) measurement with 1.5x full-scale overload capacity. The HPM720 offers diverse electrical outputs and process connections, making it a flexible, hygienic choice for industrial users prioritizing cleanliness and measurement reliability.

Key Benefits

Hygienic flush membrane design: Eliminates scaling, blockages and dead volume, meeting stringent food and pharmaceutical industry hygiene standards and simplifying CIP/SIP cleaning processes for industrial production lines.

High-temperature media compatibility: Optional customized cooling fins efficiently dissipate heat, enabling reliable measurement of high-temperature liquids/gases—ideal for food and beverage processing (e.g., pasteurization, brewing).

Broad pressure measurement range: Covers both gauge and absolute pressure from low vacuum (-100kPa) to 2.5MPa, supporting diverse industrial applications from liquid level measurement to high-pressure process control.

Robust 316L stainless steel construction: Resists corrosion from acidic/alkaline industrial fluids and harsh cleaning agents, ensuring a long service life in hygienic production environments.

Flexible integration for industrial systems: Offers multiple output signals (420mA, 420mA+HART, 05VDC, 010VDC) and tri-clamp process connections, compatible with existing industrial control systems and easy to install/replace.

Stable long-term performance: Delivers ±0.5%FS accuracy at 25℃ and ±0.50%FS/year stability for ≤100kPa (±0.25%FS/year for >100kPa), reducing calibration frequency and operational costs for hygienic industrial facilities.

Industrial Applications of Sanitary Pressure Transmitter

This sanitary pressure transmitter is optimized for industrial users in hygienic and process-intensive sectors, with core applications including:

Food & beverage industry: Ideal for pressure/level measurement in dairy processing, brewing, beverage production and meat packaging—supporting hygienic production and compliance with food safety regulations.

Pharmaceutical manufacturing: Suited for drug formulation, sterile production and biotech processes, where clean-in-place (CIP) and sterilize-in-place (SIP) compatibility is mandatory.

Medical device production: Enables hygienic pressure measurement for medical fluid processing and sterile packaging, meeting medical device manufacturing quality standards.

Industrial liquid level measurement: Accurately measures liquid levels in hygienic storage tanks and processing vessels for chemicals, cosmetics and personal care products.

General industrial process control: Used for pressure monitoring in non-hygienic industrial processes with viscous fluids or easy-scaling media, such as paint and adhesive production.

FAQ

What tri-clamp sizes does the HPM720 Sanitary Pressure Transmitter support?

The HPM720 is available in standard 1.5'' and 2'' tri-clamp sizes, the most common hygienic process connection sizes for food, pharmaceutical and beverage industrial production lines. Custom clamp sizes are available upon request for specialized equipment.

Can the HPM720 Sanitary Pressure Transmitter measure viscous fluids without blockages?

Absolutely. Its flush flat diaphragm design eliminates dead volume and direct contact between the sensor and viscous fluids, preventing blockages and scaling—making it perfect for measuring syrups, creams, pastes and other viscous industrial media.
