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 temperature 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 for temperature monitoring

• 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)

* Probe and cable length, straight and right-angle options are available. A lug-mount adapter is available for TT420S-LT.

Optional Magnet Mount Adapter for TT420S-LT

   • Accepts 3/8-16 UNC sensor thread (TT420S-LT only)
   • Used when permanent mounting is not practical or not possible
   • Solid brass for rapid temperature conduction
