HE-960CW

Panel-mount Type Conductivity Meter (Four-Wire Transmission, 2-channel)

HE-960CW connects conductivity sensor (ESH /FS Series) and measures conductivity and temperature in the sample water. It is ideal for the conductivity control of the purified water, pasteurized water, and water for injection that are used in the production of pharmaceuticals.
And we have developed a lineup of electric conductivity sensors that can be used in conjunction, from the conventional insertion type to the flow-through type with improved cleaning and sanitary properties.

Transmission output	Number of outputs: 4 4 mA to 20 mA DC/0 mA to 20 mA DC, input/output isolated type Maximum load resistance: 900 Ω Transmission output range: Freely selectable within the measurement range(Negative terminals of each transmission output channel are connected inside and thus have the same electric potential.)
Contact output	Number of outputs: 4 Alarm contact outputs (R1, R2, and R3) Contact type: relay contact, SPST (1a) Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load) Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis. Output contents: selectable from the selected measurement, USP assessment,anomaly alarm and maintenance. Alarm contact output (R4) Contact type: relay contact, SPDT (1c) Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load) Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis. Output contents: selectable from the selected measurement, USP assessment,anomaly alarm and maintenance. (However, R1 and R2, and R3 and R4 share the common contacts respectively.) Contact operation (operation between C and NO for R1 to R4) When selected measurement, USP assessment, or maintenance is selected in output contents: Contact point becomes “CLOSE” at control operation and “OPEN” at normal state (including power shutdown). When anomaly alarm is selected in output contents: Contact point becomes “CLOSE” at normal state and “OPEN” at anomaly state (including power shutdown). (When between C and NC is used with R4, contact point becomes reverses state with that of between C and NO.)
Communication output	RS-485 input/output
Calibration function	Conductivity: Based on the specified compensation coefficient for cell constant (parameter input). Temperature: Calibrated by comparing with the reference thermometer. TDS: Conversion using a user-defined coefficient value (0.30 to 1.00).
Transmission output hold feature	Previous value hold Optional value hold Selectable from the above (However, only the previous value hold is available in the maintenance mode.)
