Pressure Transducers
QPress – QLS-COMBO 3100 Series
The QLS-COMBO 3100 Series puts pressure and temperature measurement in one stainless-steel probe, returning a 4–20 mA pressure signal alongside a PT100 or PT1000 output. Engineers gain both readings from a single process tap and one cable run, which cuts installation points on skids, compact plant and test rigs. With ranges to 40 bar, a <= 1 ms response and 200 % overload, it stays accurate where space, wiring and process conditions are demanding.

Key Features
- One probe returns both pressure (4–20 mA) and temperature (PT100/PT1000), cutting process taps and wiring.
- ±0.5 % FS (±0.25 % optional), <= 1 ms response and 200 % overload for fast, robust process duty.
- Stainless steel 304 wetted parts for broad media compatibility.
Typical Applications
