Reliable Solutions for Low Pressure Measurement in Boilers and Furnaces
Draft pressure transmitters are designed to measure very low pressure ranges. They are essential in boilers, furnaces, and ventilation systems where negative or low positive pressures must be monitored with high accuracy. Yokogawa’s EJA120E and EJX120A series transmitters stand out with high accuracy, long‑term stability, and DPharp digital sensor technology.
These models serve as natural references for searches such as “boiler draft pressure transmitter” and “furnace low pressure transmitter.”
