Application of High-Temperature Pressure Transmitters in Pharmaceutical Moist-Heat and Dry-Heat Sterilizer Systems

High-temperature pressure transmitters are specially designed for pharmaceutical production environments. They are widely used in pharmaceutical moist-heat sterilizers and dry-heat sterilizer systems to monitor monitor chamber and supply-line pressure, support sterilization cycle control, provide safety interlocks and control internal pressure in real time under high-temperature sterilization conditions, generating traceable data for related compliance requirements.

What is the advantage of high-temperature pressure transmitters applied in Pharmaceutical Moist-Heat and Dry-Heat Sterilizer Systems?

Moist-heat sterilizers rely on saturated steam and pressure–temperature correlation, while dry-heat sterilizers rely on high-temperature hot-air circulation; therefore, pressure measurement plays different roles in the two systems. With high precision, high temperature resistance and strong stability, the high-temperature pressure transmitters ensure stable and compliant sterilization processes, meeting GMP pharmaceutical production standards.

What are the scenarios of application of high-temperature pressure transmitters?

1.Application of High-Temperature Pressure Transmitters in Moist-Heat Sterilizer Systems

Moist-heat sterilizers typically operate at 121°C or 134°C using saturated steam. Pressure measurement by using high-temperature pressure transmitters will support steam saturation control, vacuum and leak testing, cycle reproducibility, safety protection, and batch record generation.

2.Application of High-Temperature Pressure Transmitters in Dry-Heat Sterilizer Systems

Dry-heat sterilizers use hot-air circulation, typically at 160–250°C or higher, for sterilization and depyrogenation. Pressure is not the primary sterilization parameter; however, pressure or differential-pressure monitoring by using high-temperature pressure transmitters will support to monitor airflow direction, filtration of HEPA High Efficiency Particulate Air Filter, chamber pressure balance, and safety interlocks.

What Are The Key Points of Validation Notes?

For moist-heat sterilizers, it is necessary to ensure pressure data supports of high-temperature pressure transmitters saturated steam temperature control, leak testing, and cycle release. 

For dry-heat sterilizers, it is necessary to monitor pressure and differential-pressure stability for airflow direction, HEPA filtration, and chamber balance by high-temperature pressure transmitters. 

Summary

Moist-heat and dry-heat sterilizers are core equipment in pharmaceutical and biotech industries. They rely on precise pressure control to guarantee sterilization effect.

High-temperature pressure transmitters continuously detect internal pressure inside sterilizers in high-temperature environments. The real-time pressure signal is transmitted to the control unit, maintaining stable pressure during the sterilization cycle.

High-temperature pressure transmitters have features of high temperature resistance, good stability and anti-condensation performance which can help to meet GMP requirements, ensure sterilization reliability and reduce production risks for pharmaceutical processes.
