The Company FOX added to their range of Bimetallic Thermostats the execution of TMD4, which differs from the TM4 or TM6 series for the possibility to have two intervention point in a single instrument.This instrument, made with a compact design, gives the possibility to control the maximum and the minimum temperature of the system. Many Applications must fulfil this requirement obliging the Technicians to use two separated instruments increasing the costs of the mechanical parts and of the wiring.With the TMD4 series, we give the possibility to the customer to require, in one instrument, two different intervention values. Both the electric contacts can be chosen between the NO (Normally Open) and NC (Normally Closed).The Customer decides the two Intervention values during the order, the hexagonal body is in brass with key of 27 mm and can by supplied with hydraulic connection ½ BSPM or M22x1, both with integrated DIN3869 seal. The electric protection is IP65, the electrical connection is available with classic connector DIN30x30mm or circular connector M12x1 (IP67).• Weight - 0.07 Kg for TM4, 0.17 Kg for TM6 • Working temperature - from –20° C to + 120°C • Switching accuracy - ± 3.5° C
