Pt100 temperature transmitter HD786TR1/TR2
Sakaki Corporation Co., Ltd.
About This Product
■Summary
・For Pt100 sensor input, measurement range -200 to +650℃, scaling possible
・Built-in Pt100 sensor (HD786TR1/TR2)
・All models DC4~20mA output
・Freestanding type, wall-mounted type, DIN rail mounted type
HD786TR1, HD786TR2, HD988TR1.I, HD988TR2 are temperature transmitters for Pt100 sensor input and 4 to 20mA output (only HD786TR1 and HD786TR2 have a built-in Pt100 sensor).
Converts the measurement input of a standard Pt100 sensor (100Ω/0°C) into a 2-wire linear 4-20mA current signal. Digital linearization technology achieves high accuracy and stability. The scaling of the temperature range corresponding to 4~20mA can be freely determined in the range -200~+650℃ (minimum span 25℃) (factory default setting is 4~20mA = 0~100℃).
In addition to operation keys, the transmitter is equipped with a red LED to assist in the setting process by warning of abnormal conditions (temperature outside the setting range, sensor disconnection/short circuit). The transmitter also features reverse polarity protection. HD988TR1.I and HD988TR2 are designed to be mounted on 35mm DIN rails.
In addition to a 4-20mA analog output, the HD988TR2 also features a convenient 3½-digit digital display (10mm character height) for reading measurements. HD786TR1 and HD786TR2 can be used as freestanding or wall-mounted models.
