STI and STID converters are intended for converting the signal of Ni 1000/6180 or Pt 100/3850 resistance-type temperature sensing elements to the unified signal 4 - 20 mA. The converter consists of a plastic case, inside which the printed circuit boards and the terminal board for connection of power supply and the resistance-type temperature sensing element are placed. Two variants exist regarding to the design of the converter case:
1. STI Pt and STI Ni converters: the plastic case is made of LEXAN material, and is identical to, for example, the connection head of s 120 sensors. It is provided with a wall bracket or with a clip for attaching to a DIN console. The terminal board casing meets the IP 65 ingress protection requirements according to the EN 60 529 standard.
2. STID Pt and STID Ni converters the plastic box is made of NORYL SE1 material and is provided by a self-extinguishing retarder. It is intended for installation directly to a switchboard on a DIN console. The terminal board casing meets the IP 20 ingress protection requirements according to the EN 60 529 standard.
These converters can be utilised in any control system compatible with 4 - 20 mA current output. Standard measuring ranges of the converter are listed in the specifications table. Operating temperature range is -30 to 80°C. These limits must not be exceeded even for a short time. The sensors are designed to be operated in a chemically non-aggressive environment.
Used sensing elements: Ni 1000/6180, Pt 100/3850
