Dual DPT Sensors

Optimise and simplify your ventilation system with the Lodam DUAL differential pressure transducer (DPT). The 2-in-1 solution offers two integrated sensor elements to save space and cost and enhance functionality.

The Modbus interface also adds the option of data from an on-board and two external temperature sensors. 

The DUAL DPT sensor with Modbus is designed for our Multi Controller (LMC300) – a standard hardware platform that can be tailored to an infinite number of solutions.

The DUAL DPT sensor can also be used with other controllers via Modbus (RS485) interface.
