The 225T is a high-performance transmitter, which is based on a BCM silicone piezoresistive pressure sensor. The transmitter uses HART protocol for communicating with other devices. It has two types of wetted parts structure, with its inner-cavity type is used for gases or dilute fluid measurement, while the other type is for measuring viscous fluids or media containing solids. The unit has a pressure range, which is between 0 to 15 mbar.
It has an output signal ranging from 4 to 20 mA. The unit also has a media temperature, which measures between -40°C to +125°C. It also has an operating temperature ranging from -20°C to +80°C. The transmitter is made from 316 stainless steel material. It has a protection class of IP 65.
