01
Low-range sensitivity
Piezoresistive sensing supports differential ranges down to 10 mbar for filter loading, air movement, cleanroom pressure, and other small-pressure applications.
FGP230 / Compact differential pressure transmitter
Small pressure differences. Clear machine feedback.
A compact piezoresistive transmitter for measuring differential pressure across filters, air systems, neutral-gas circuits, and compatible liquid processes.
- Minimum range
- 10 mbar
- Best accuracy
- ±0.075% FS
- Signal options
- 4–20 mA / voltage
- Protection
- IP65 / IP67
Compact differential measurement
Resolve the pressure change before it becomes a process problem.
The FGP230 converts the difference between its high- and low-pressure ports into a stable control signal for PLCs, building controls, and monitoring systems.
02
Stainless construction
A welded stainless housing and 316L isolated diaphragm support durable service with air, neutral gases, and compatible non-corrosive liquids.
03
Field-adjustable calibration
External zero and full-scale adjustment allows installation trimming without disassembling the transmitter housing.
04
Control-ready outputs
Choose two-wire 4–20 mA or three-wire voltage output to match the PLC, building control, or data-acquisition input.

Configuration paths
Built around the machine, not a shelf number.
Differential range
Select full scale so the normal operating differential uses roughly 60–80% of the range while retaining margin for transients.
Port geometry
Match both high- and low-pressure ports to tubing, manifolds, or direct process connections and confirm sealing method.
Signal and connector
Choose 4–20 mA or voltage feedback with DIN, M12, or cable termination around the control hardware and enclosure rating.
Media and materials
Confirm air, neutral gas, or liquid compatibility and select the housing, diaphragm, and sealing materials for the process.
Ordering matrix
Build the configuration.
Choose one option at each position. The live string follows the supplied ordering sequence while replacing the source series name with FGP230.
