Conductivity transmitter with programmable outputs. Conductivity and Envelope Dimensions [mm] (see datasheet for details)
temperature output via single or dual analog 4-20 mA. Two transistor out-
puts are also included. Transmitters are engineered for a wide scope of
measuring ranges and can be delivered in 2-wire or 3-wire configurations.
Intelligent, integrated, beautiful design fits perfectly with an assortment of
easily configured fittings.
