Typical Applications
Semiconductor & Coating Processing Equipment
Vacuum coating, PECVD, sputtering and comparable manufacturing processes are extremely sensitive to any variation in chamber vacuum pressure.
The HNP50 employs a fast-response high-resolution MEMS sensing core. Its RS485 communication port enables seamless integration into PLC closed-loop control setups, supporting precise pressure regulation as well as critical safety interlock functions.
Vacuum furnaces and heat treatment systems.
Processes like brazing, quenching, and annealing involve significant temperature swings, posing a challenge regarding sensor thermal drift. Thanks to its ceramic capacitive sensing element and multi-point temperature compensation, the HNP50 demonstrates well-controlled drift in actual operation, eliminating the need for frequent recalibration.

Why Choose Our Products ?
We produce the core sensing element in-house, which lets us guarantee consistent stock availability and fully traceable component specifications. Any technical problems can be resolved by directly tuning the base compensation curves-there is no reliance on slow response times from external upstream vendors.
The sensor's overload resistance delivers tangible real-world benefits. Vacuum installations frequently see sharp pressure surges caused by operator misoperation or slow valve response. This unit survives peak pressures up to ten times its rated range with no permanent damage, cutting unplanned field replacements and associated maintenance overheads.
A full suite of output interfaces comes as standard, paired with straightforward wiring flexibility. Available signal types include 4–20mA with HART for remote indicators, RS485 for direct PLC connection, and 0–10V analogue output for DAQ modules. One single part number covers all typical project requirements; configuration only requires rewiring, streamlining your spare parts and procurement inventory.
