The TGT70 thermometer has both an electrical output signal and an onsite display, yet requires no external power supply. This expansion thermometer for industrial applications operates in the temperature range of –40 to 250°C, and has selectable output signal of 0.5–4.5 V and 4–20 mA. With the new device, temperature can be precisely controlled and adjusted. — Wika Alexander Wiegand SE & Co. KG, Klingenberg, Germany
