Vacuum Measurement & Control
Precision Vacuum Measurement & Control
In the pursuit of Extreme High Vacuum (XHV) and Ultra-High Vacuum (UHV), the ability to quantify total pressure with absolute repeatability is the defining factor in process stability. AIMRSE provides an advanced portfolio of vacuum metrology solutions designed to bridge the gap between atmospheric pressure and deep vacuum regimes. Our systems leverage diverse physical principles—from Pirani-based thermal conductivity to Bayard-Alpert hot cathode ionization—to deliver high-resolution data across a 13-decade dynamic range. By integrating sophisticated signal processing with low-leakage transducer architectures, we ensure that every millivolt of output translates into actionable intelligence for semiconductor fabrication, thin-film deposition, and complex gas-phase analytical chemistry.

Product Portfolio
Vacuum Gauge Tubes
AIMRSE gauge tubes are engineered for high-fidelity pressure transduction in the most demanding environments. Our portfolio includes convection Pirani tubes for rough-to-fine vacuum and hot/cold cathode ionization sensors for UHV regimes. Featuring yttria-coated iridium filaments for enhanced chemical resistance and specialized ceramic feedthroughs to minimize outgassing, these transducers offer unparalleled long-term stability. Each unit is calibrated to provide linear response curves, ensuring seamless integration into research-grade beamlines and industrial process chambers.

Vacuum Transmitters
AIMRSE active transmitters consolidate the sensor element and drive electronics into a single, compact digital footprint. Designed for Industry 4.0 compatibility, these transmitters convert complex physical signals into standardized 4-20mA, RS485, or EtherCAT outputs. With onboard temperature compensation and microprocessor-driven linearization, our transmitters eliminate the need for external controllers in decentralized architectures. Their robust electromagnetic compatibility (EMC) shielding ensures reliable operation even in the vicinity of high-frequency RF generators used in plasma etching.

Vacuum Controllers
The AIMRSE controller series provides the central intelligence for complex vacuum manifolds. Supporting simultaneous inputs from multiple gauge technologies, these controllers feature high-speed logic processors to manage setpoint relays, valve sequencing, and safety interlocks. The intuitive HMI allows for real-time visualization of pressure trends and system health diagnostics. Whether managing a simple laboratory station or a multi-stage industrial pumping rack, our controllers provide the precision and reliability required for automated vacuum process management.

Customer Reviews
"The integration of AIMRSE's active vacuum transmitters into our high-vacuum thin-film coating system has significantly improved our process yield. Specifically, the combination gauge's ability to handle the transition between the Pirani and Cold Cathode regimes without signal jitter was far superior to our previous vendor's solution. This stability allowed our automated PLC to initiate the deposition process with micro-Torr precision, reducing film defects by 15%. Their technical support team's recommendation to use yttria-coated filaments for our specific gas mix demonstrated a deep understanding of vacuum sensor life-cycles and outgassing physics."
