Pressure Transducer: Pressure Range 0-100 kPa, IP Rating IP67

Q: How does this pressure transducer detect packaging leaks?

It measures pressure differentials during vacuum or pressure decay tests. A stable pressure indicates proper sealing, while pressure changes signal leaks or weak seals.

Q: What maintenance does this transducer require?

Regular calibration every 6-12 months, visual inspection for diaphragm damage, cleaning of pressure ports with food-safe solvents, and verification of electrical connections.

Component Specifications

Definition

A precision electromechanical device that converts applied pressure into an analog or digital electrical signal, specifically designed for monitoring and verifying seal integrity in automated food packaging systems. It measures differential or gauge pressure to detect leaks, weak seals, or packaging defects in real-time during production.

Working Principle

Operates on the piezoresistive or capacitive sensing principle where pressure causes deformation in a sensing diaphragm, changing electrical resistance or capacitance proportionally. This change is converted via Wheatstone bridge circuits or capacitance-to-digital converters into standardized output signals (4-20mA, 0-10V, or digital protocols like Modbus).

Materials

Stainless steel 316L diaphragm and housing, Viton or PTFE seals, ceramic or silicon sensing element, gold-plated electrical contacts, epoxy encapsulation for moisture protection
