STD-T 4 ... 20 mA / HART
STD-T temperature transmitter is ideal for control and temperature measurement in industrial processes with precision, stability and linearity.It uses a technology known as Pt-100 or RTD, the RTD consists of a resistance in the form of high purity platinum wire encapsulated in ceramic and mineral insulating bulb, are based on the principle ohmic resistance variation as a function of temperature proportional and direct way. The temperature transmitters transform the value of Pt-100 resistance thermometer in current values (mA) or voltage (V) which is directly proportional to temperature.
5 digit multifunction LCD display, allows the user to view the measured variable in PV (process value), and current percentage in addition to having a permanent bar graph with real-time reading.STD transmitter provides analog signal current of 4 ... 20mA, it can be re-configured remotely using Hart communication protocol.All STD transmitters are made in full in Stainless Steel 316 or Aluminum head both with acrylic window on the cover that makes the display always visible.
Made with a wide range of process connections such as: thread, flange, sanitary and accessories such as neck extended to high temperature, well or adjustable cable gland to meet the high market demand.
