Sensorex CT-1000 Operating Instruction

Specifications/Operating Instruction

General Description

The model CT-1000 (encapsulated miniature transmitter) is a 2-wire, 4-20mA blind conductivity

transmitter featuring encapsulated construction, high performance and compact size.

Connect a conductivity cell of k=0.1 or 1.0 to it to then transform the output to a 4-20mA current

proportional to the conductivity level. This output may be transmitter over 2 wires to a control

location. The same 2 wires provide power to the transmitter. Any DC power supply from

12 to 36V DC may be used. There are two adjustments on the transmitter to standardize the

conductivity output marked as "SPAN" and "ZERO". The output can be monitored with a loop-

powered meter, a loop resistor or a multimeter during the standardization process.

Page 2 Installation 1. Two 6-32 mounting holes 9” centers are provided. The transmitter can be mounted in a head, weather-proof box, or DIN rail. 2. The output wires are isolated from ground; connections are made at the terminal strip observing polarity to the terminals marked + , -out. These wires are to be connected to a DC power supply through a load resistor.
