Measurement & Control Instrumentation
We are the U.S. distributor for FISCHER Mess- und Regeltechnik GmbH, the family-owned German manufacturer based in Bad Salzuflen and a specialist German maker of measurement and control instrumentation. We source and stock the full FISCHER range across five disciplines, covering pressure, differential pressure, flow, level, and temperature/humidity, so North American plants can buy and service German-built instruments without long import lead times.
FISCHER's strongest niche is differential pressure, and we stock the PRO-LINE family led by the DE90 digital differential-pressure transmitter. It resolves pressure down to the single-pascal level, with measuring ranges from roughly 0 to 25 Pa up to 0 to 25 kPa, a piezo-resistive sensing element, an integrated display, and configurable alarm outputs. Output and interface options include 0/4-20 mA, 0/2-10 V, and 1-5 V analog signals plus IO-Link and RS485 Modbus RTU for digital integration.
Beyond DP, we supply FISCHER pressure transmitters (relative and absolute), thermal/calorimetric flow switches and monitors, fill-level instruments, humidity and temperature devices, signal conditioners/converters, and valves. Typical applications we support include filter and dust-collector loading, cleanroom and containment pressure cascades, HVAC air-pressure control, and process-skid transmitters.
We help match the right instrument to the job (evaluating measuring range, media compatibility, output signal, and process connection), and we hold replacement stock so a failed transmitter or switch does not stall production. Request a quote and we typically respond within one business day.

Typical Applications
- Filter, bag-house, and dust-collector differential-pressure monitoring to signal clogging and trigger cleaning cycles
- Cleanroom, laboratory, and containment room-pressure cascades to maintain positive/negative pressure
- HVAC and building air-handling systems for duct and filter pressure control
- Process skids and OEM machinery requiring compact 4-20 mA or IO-Link/Modbus transmitters
- Compressed-air, gas, and liquid flow monitoring with calorimetric flow switches
- Tank and vessel level monitoring in process and utility systems
Fischer: Common Questions
For low-range air differential pressure the DE90 PRO-LINE transmitter is the workhorse, covering roughly 0 to 25 Pa up to 0 to 25 kPa with a display and adjustable alarms. Tell us your range, media, output signal, and process connection and we will spec the exact model.
FISCHER transmitters offer analog 0/4-20 mA, 0/2-10 V and 1-5 V signals, plus digital IO-Link and RS485 Modbus RTU on models like the DE90, so they integrate with most PLC and building-automation systems.
No. FISCHER is a full-line manufacturer. We also supply pressure transmitters, flow switches and monitors, level instruments, temperature/humidity devices, signal conditioners and valves, all of which we can source and stock.
