Temperature Sensors with 4-20 mA Output and Liquid-Tight Conduit Fittings
Features • 2-wire, loop-powered 4-20 mA analog output • Attachment probe, sensor, 2-wire 4-20 mA signal conditioner and conduit fitting in one • No user calibration: works right out of the box • Compatible with PLCs, meters, data acquisition, and hazard monitoring systems • Reverse-wiring protected • Integral 1/2 in flexible liquid-tight conduit fittings • Optimized for Class II area hazard monitor systems (e.g. grain, coal dust) • FM approved, Dust Ignition-proof. Class II and III, Div I (E, F, G); NEMA 4
TT420-LT probes and fittings are optimized for shaft bearing (TT420Z-LT), belt rub-block (TT420S-LT) and other temperature measurement applications. All models have integral liquid/dust-tight conduit fittings allowing complete sensor and cable segregation and protection.
2 model families
TT420S-LT* - 3/8 - 16 threaded stud probe (e.g. belt-alignment rub block temperature)
TT420Z-LT* - 1/4 in stainless steel probe with 1/8 NPT adapter (e.g. zerk grease fitting for bearing temperature)
