SPCP-20 pH transmitter two-wire system

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).
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.
