Product Details
1. General Introduction
EJA118E Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. It's diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly, connected to the transmitter using capillaries filled with fill fluid, available for fluid with temperature -50 to 310°C.
