The pH transmitter APX1-C2 is an instrument used to measure and monitor the acid-base properties of liquids, that is, the pH value. It has a wide range of applications and can provide reliable performance in various industrial and laboratory environments. pH measurement and control functions. The pH value is an important parameter that describes how acidic, neutral, or alkaline a liquid is. It usually ranges from 0 (extremely acidic) to 14 (extremely alkaline). The pH transmitter APX1-C2 has the functions of two relays, two current outputs and one RS485 communication interface.
Two-way relay: These relays are often used to implement pH-based control or alarm functions. For example, when the pH of a solution exceeds or falls below a set threshold, a relay can trigger corresponding actions, such as opening or closing a valve, pump, or other device. This helps automate process control, ensuring the pH is always within the desired range.
Two current outputs: These current outputs are typically used to transmit pH measurements to a monitoring system or recorder. By converting the pH value to a standard current signal (e.g. 4-20 mA), the data can be easily transmitted to remote devices for data logging, analysis and monitoring.
One RS485 communication interface: RS485 is a communication protocol usually used for data communication with other instruments, control systems or computers. Through the RS485 interface, the pH transmitter can be connected with other devices to achieve real-time data transmission, remote monitoring and control. This also allows users to integrate pH transmitters into industrial automation systems for more complex control and data management functions.
The pH transmitter APX1-C2 with two relays, two current outputs and one RS485 communication interface has powerful control, monitoring and data transmission functions. They can be used in a variety of applications, including chemical industry, environmental monitoring, food processing, pharmaceuticals, etc., to ensure precise control and data recording of acid and alkaline processes.
