Dwyer Instruments / Love Controls 26133-926-934 Temperature / Process Controller

The Dwyer Instruments / Love Controls 26133-926-934 is a microprocessor-based temperature and process controller from the 2600 Series. It delivers precise monitoring and control across industrial heating, cooling, and process applications through universal sensor inputs and configurable control logic. The unit accepts thermocouples (J, K, E, T, L, N, B, C, S, R), RTDs (100Ω Pt NIST, 100Ω Pt DIN, 120Ω Ni Industrial, 1000Ω Pt DIN), differential inputs (-10 to +10 mV DC), and process signals (0 to 20 mA DC, 0 to 10 VDC).
