6.3.11 Dual CT (Conductivity/Temperature)
The inputs can be any combination of the following ProMinent sensors;
2-wire boiler conductivity, 4-wire cooling conductivity, 4-wire condensate conductivity, LM335¹ (10mV/°K), Pt100 or Pt1000
temperature sensors.
No other conductivity sensors will match the input circuitry.
Temperature can be used for display, control or compensation.
Do not exceed 30 meters, 100 feet, of cable length.
FOOTNOTE 1: LM335 is our SGT sensor, pn 1051507
NOTE: The Prominent Toroidal conductivity sensor emits a 4-20mA signal and therefore requires a 4-20mA input driver.
NOTE: To lengthen a temperature sensor signal, use the temperature transducer and input this signal on a 4-20mA input
card.
