Micro Differential Pressure Transmitter with Adjustable Range & LCD Display
High-precision micro differential pressure transmitter with MEMS sensor and temperature compensation. Features adjustable range, configurable response time, and digital LCD display — ideal for fans, filters, clean rooms, and HVAC applications.
The LEFOO LFM11 Micro Differential Pressure Transmitter is a compact, high-accuracy instrument designed for air and neutral gas pressure monitoring. Built around a precision MEMS sensing element, it offers digital pressure acquisition, temperature compensation, and a stable, long-term output suitable for demanding environmental and industrial applications.
The transmitter supports positive, negative, or differential pressure detection, with a switchable pressure range and selectable units configurable directly on site via a built-in DIP switch. The response time (0.5–4 seconds) can also be adjusted to match application requirements.
Housed in a flame-retardant ABS enclosure with excellent impact and heat resistance, the LFM11 includes a large LCD digital display for clear visualisation of pressure readings. Easy to install using its mounting back plate, it can be securely fixed or quickly removed for service and recalibration.
Designed for fans, blowers, filters, ventilation ducts, and cleanroom pressure monitoring, this transmitter delivers consistent accuracy and reliability for air handling, HVAC, and building automation systems.
