Minco Platinum 1000 Ohm Space Temperature Transmitter TT859

Minco Platinum 1000 Ohm Space Temperature Transmitter


The Minco TT859 Platinum 1000 Ω Space Temperature Transmitter is DIP switch rangeable. Non-interacting multi-turn controls provide a constant resolution adjustment. Gold-plated DIP switches ensure stable overlapping incremental selections between -10° to 60℉ (-23 to 15℃) for zero and 35° to 150℉ (2° to 66℃) for span. The well ventilated housing allows quick and accurate temperature sensing and effective heat dissipation from the circuit. Repeatability is excellent because the TT859 uses a platinum RTD as the sensing element. Calibrated system accuracy of the TT859 is typically 0.25℉ (0.14℃) with optional sensor matching.Once installed, it can be field-calibrated or re-ranged through coarse switch adjustments and fine tune with multi-turn zero and span pots. The two-wire termination points are insensitive to power supply polarity. This prevents reversed hookups and simplifies installation.
