Siemens Energy & Automation”s SITRANS P ZD pressure transmitter measures pressure, absolute pressure, and level of liquids and gases. The transmitter indicates and monitors the pressure measured at the point of installation and is available in an axial and a radial version. The transmitter can be easily and conveniently user configured by using the set of three keys just underneath the housing cover. The transmitter features an integrated five-digit display that shows measured pressure and upward and downward violation of limits. Measuring range adjustment is maximum 1:10. The pressure transmitter is comprised of a thin-film measuring cell with a ceramic diaphragm, the electronics, and the digital indicator, all in a compact stainless steel housing with glass cover and a stainless steel process connection. The output is standard four to 20 mA with a measuring accuracy of (typical) < 0.25 percent. There are various modes of operation available, including: measured value, password, dimension, start of scale and end, upper and lower limit value, zero adjustment, upeer and lower current saturation limit, and electrical damping.
