TEJ / CATALOGUE SELECTION
From field readings to connected records.
Review signal options on catalogue instruments, including 4–20 mA, voltage, HART and RS-485 where specified. Gateways, acquisition and control-system integration are selected separately around your architecture.
01 / PROCESS SENSING
Pressure & temperature
TEJ / CATALOGUE
Select compact transmitters, process instruments or local gauges for pumps, compressors and hydraulic systems. Match the measuring span, overload capacity, wetted materials and connection to the medium. Confirm the total error at operating temperature.
- Range options
- 0–0.4 to 0–1600 bar
- Outputs
- 4–20 mA / 0–10 V
View specifications
- Range options
- 0–0.4 to 0–1600 bar; vacuum variants.
- Units
- bar, psi, kPa, MPa or kg/cm².
- Outputs
- 4–20 mA or 0–10 V; smart variants by model.
- Max. error guide
- ±0.25 / ±0.5 / ±1% span at adjustment temperature.
- Wetted parts
- Stainless steel; diaphragm and seals to suit the media.
Indicative industry selection data, not guaranteed ASTREON model ratings. Confirm the final range, accuracy and configuration against the selected manufacturer datasheet.
03 / ENVIRONMENTAL MEASUREMENT
Humidity, gas & dew point
TEJ / CATALOGUE
Monitor air humidity and temperature using wall, duct or remote-probe arrangements. Select the filter and mounting for contamination, airflow and maintenance access. Accuracy must be assessed across the actual humidity and temperature conditions.
- Relative humidity
- 0–100% RH
- Outputs
- Voltage / RS-485
View specifications
- Relative humidity
- 0–100% RH.
- Temperature guide
- −40 to +80 °C, probe-dependent.
- Accuracy example
- ±1.5% RH at 0–90% RH and 0 to +40 °C.
- Outputs
- Voltage or RS-485, selected by model.
- Construction
- Room / duct / remote probe; suitable filter.
Indicative industry selection data, not guaranteed ASTREON model ratings. Confirm the final range, accuracy and configuration against the selected manufacturer datasheet.
TEJ / CATALOGUE
Specify the target gas first. Electrochemical, infrared and catalytic technologies serve different gases. Confirm units, cross-sensitivity, calibration and alarms. Any hazardous-area approval must match the exact instrument configuration and installation.
- Oxygen example
- 0–25% vol O₂
- Combustible guide
- 0–100% LEL
View specifications
- Oxygen example
- 0–25% vol O₂; gas-specific sensor.
- Combustible guide

- Toxic gases
- ppm ranges selected for CO, H₂S and other gases.
- Signal options
- 4–20 mA / HART; relays or fieldbus by model.
- Selection checks
- Gas, response, calibration and exact approvals.
Indicative industry selection data, not guaranteed ASTREON model ratings. Confirm the final range, accuracy and configuration against the selected manufacturer datasheet.
Catalogue ranges, accuracy, approvals and operating conditions depend on the selected model and application. Detailed specifications are confirmed with your requirement.
