Description
The Laurel Laureate RTD meter is a 1/8 DIN temperature panel meter and controller, factory calibrated for Pt100 (DIN and ANSI), Ni120 and Cu10 sensors. It reads the full range of each sensor (−200 to +850 °C for Pt100) with ±0.01% of span accuracy plus conformity error, at selectable 1°, 0.1° or 0.01° resolution in °C, °F, K or °R.
2-, 3- and 4-wire connections are supported with lead-resistance compensation, and adaptive filtering steadies readings in noisy plants. Options include alarm/control relays, an isolated 4–20 mA or 0–10 V output and Ethernet, USB or RS485 Modbus communication.
