AGP2112 capacitance diaphragm gauge for absolute-pressure measurement from 0 to 100 Torr. The source record states ±0.3% of reading accuracy, ≤60 ms response, 0–10 V output, RS-485 Modbus RTU, TFT display, 15–30 V DC supply and a KF16 connection.
Description
ASAIR AGP2112 Capacitance Diaphragm Vacuum Gauge
The AGP2112 is the 0–100 Torr member of the AGP21 capacitance diaphragm gauge family. Diaphragm displacement is converted into a linear absolute-pressure signal that is substantially independent of gas thermal or ionization properties.

For the stated full scale, a linear 0–10 V output corresponds nominally to 0.1 V per Torr. The exact transfer function and connector pinout for the supplied revision take precedence.
Typical uses include controlled vacuum processes, coating, plasma systems, packaging, drying and research equipment. Confirm wetted-material compatibility, zeroing conditions, overpressure rating, mounting orientation, digital register map and calibration certificate before use.
