德國burkert 8400帶顯示溫度傳感器 The switching points can be programmed with the 3 key pads or optionally, with input 4 - 20 mA, from an external PLC over a 4 - 20 mA loop. 德國burkert 8400帶顯示溫度傳感器 As an option, the process value can additionally be transmitted to the PLC (4 - 20 mA). The connection of the 8400 to the process in the piping is made using standard fittings.
