Product description
Technical indicators
- product description:
 
CP series two-wire pH analyzer / transmitter Model: PCP-20T / SPCP-20T
 
- Features:
 
Sturdy aluminum alloy shell, adjustable installation angle
 
Easy operation, adjustable measuring range, automatic correction and self-diagnosis through built-in microprocessor electrode
 
Front operation, front wiring
 
Model SPCP-20T is an intrinsically safe type with IEC explosion-proof certification, certification number: C12661 ~ C12664
 
 
 
- Product advantages:
 
Manual temperature compensation: For the pH electrode without temperature compensation resistor, manual temperature compensation can be performed through the external temperature sensor of the transmitter
 
Temperature compensation range: 0 ~ 100 ° C.
 
Sample pH temperature compensation: pure water or boiler feed water temperature compensation through temperature coefficient
 
Temperature compensation coefficient range: -0.100 ~ + 0.100pH / ° C.
 
-Self-diagnosis function:
 
In the following alarm conditions, the output signal can be switched to high or low output:
 
-The glass electrode is cracked or broken
 
-Disconnection or short circuit of temperature electrode or wire
 
- hardware malfunction
 
- data error
 
-Measurement / maintenance mode selection:
 
In maintenance mode, the measured sample pH value is displayed, and the output signal remains at the previous measured value, set value or actual measured value (user setting).
 
-Note:
 
When using the junction box to extend the electrode cable, it is recommended to use the original cable (model: EC-10). Electrode cables and extension cables should be kept away from electrical noise sources, such as power lines.
