ensure the barbed interfaces are seated correctly to prevent bypass leaks in your HVAC control systems

Dual-Power Versatility: Operates on 20-30Vac hardwire or AA batteries

Key Benefits for the Contractor Wide Operating Range: Covers a broad spectrum of low-side monitoring from vacuum to 100 psi

Calibration is performed by adjusting the zero and span settings to ensure the 3-15 psig output aligns precisely with the 50-150°F scale using a precise pressure gauge and a known temperature reference

Belimo NMQB24-MFT Actuator Els PW 17895 ensure the barbed interfaces areThe Belimo NMQB24 MFT Actuator is a non spring return, high speed solution designed for precise proportional damper control in commercial HVAC systems. Delivering a steady 70 in lb torque, this multifunction technology (MFT) actuator offers field programmable flexibility via 24Vac dc power. It natively supports a 2 10Vdc control signal, but remains adaptable for 4 20mA modulation (using a 500 Ohm resistor), PWM (1500 Ohm), and floating point or on off
