DESCIPTION

The BASI intelligent non-isolated transmitter BTT785, is available in casings for in-head and for DIN-rail mounting as well as mounted into an IP65 protection box. This transmitter allows the user to: select sensor and input signal type, select and adjust input range, perform offset correction and device calibration, specify input ranges and output type (4-20 mA or 20-4 mA), select decimal point position and measurement unit, select output reaction at sensor break, adjust the digital filter. The BTT785 transmitter is easy to program via the specialized configuration software "TraCon". Thanks to its large capabilities and low price, BTT785 can be very useful in various industrial applications requiring temperature conversion before following measurement and control.
