All products
Three product families, one engineering team
Every series shares the same design rules: sealed aluminium or 316L housings, wide-temperature electronics, and interfaces that speak Modbus, ONVIF or HART.
Imaging & Surveillance
Visible, thermal and explosion-proof camera systems for process observation, remote inspection and perimeter security.
6 seriesRadar & Detection
60 GHz presence sensors, traffic and ground surveillance radar, and 80 GHz radar level transmitters.
5 seriesTest & Measurement
Gas detectors, thermal imagers, ultrasonic flow meters, pressure calibrators and vibration analyzers.

Why SENTIRA
Built to be installed, not returned
01
Environmental first
Every housing is tested at the temperature it is rated for, not at 25 °C. Sealing is verified by immersion, not by a datasheet claim.
02
Calibration traceable
Pressure and temperature references are calibrated against standards traceable to NIST, with a certificate in the box.
03
Open interfaces
ONVIF, Modbus RTU/TCP, HART and 4-20 mA. No proprietary gateway required to integrate with an existing SCADA or VMS.
04
OEM from 50 units
Your logo, colour and firmware defaults, with the same hardware platform and the same two-year warranty.
Applications
Where our instruments end up
Four industries account for most of our shipments, each with its own certification and interface requirements.
Mining & heavy industry
Belt conveyors, crushers and refuse piles monitored from a single PTZ, with thermal detection for spontaneous combustion.
Oil, gas & petrochemical
Explosion-proof stations and 80 GHz level transmitters certified for Zone 1, from tank farm to flare line.
Smart city & traffic
ANPR, speed radar and multi-lane classification for tolling, enforcement and junction management.
Manufacturing & inspection
Borescopes, thermal imagers and vibration analyzers for predictive maintenance and incoming inspection.
How we work
