MU-Analog-65
Differential Pressure Transmitter (analog)
Combination of mechanical ring balance and integrated transmitter. Three outputs as standard: 4–20 mA, 0–20 mA and 0–10 V. Analog scale display and signal output for building management and SCADA systems.
- Three outputs as standard: 4–20 mA, 0–20 mA, 0–10 V
- Analogue 150×150 mm scale as standard
- Supply selectable: 24 VAC / 110 VAC / 230 VAC / 24 VDC
- No drift — purely mechanical measuring path
- No readjustment required
- Mechanical low-pass at small spans — steady output without post-filtering in the controller
Scale and unit are printed at manufacture and cannot be changed afterwards.
All three outputs (4–20 mA · 0–20 mA · 0–10 V) are standard regardless of supply choice.
* Required at order time — cannot be changed afterwards
Mechanical measuring path + 4–20 mA output: the best of both worlds
Electronic differential pressure sensors have documented drift rates of 0.2 to 1 % of full scale per year. On a 50 Pa sensor that means up to 2.5 Pa deviation after five years — for a cleanroom pressure cascade of 15 Pa, that is one-sixth of the monitored value. The MU-Analog-65 moves the measurement into a purely mechanical ring balance. The transmitter only converts the rotation angle — it is not itself the sensor. The measurement does not drift, physically.
At the same time, the MU-Analog-65 provides three transmitter outputs — 4–20 mA, 0–20 mA and 0–10 V, all included as standard — for direct connection to building management or SCADA systems. The mechanical 150×150 mm scale is also included as standard — readable even during power loss.
For those who want to reduce wiring to two cores (retrofit, cramped terminal boxes), the MU-Analog-65-2L is the right choice. Same mechanics, passive 2-wire transmitter.
