Suitable for on-site RTD and thermocouple temperature sensors, converting their resistance/mV signals into isolated 4-20mA or similar signals before transmitting them to PLC/DCS systems. Addressing the following scenario challenges: <p> ① Signal interference and data instability between instruments and systems. <p> ② The interface signals between the instrument and the system are different, requiring signal conversion. <p> ③ One-way signal transforms into multiple signals, supplying automated instruments and control systems. </p></p></p>
Suitable for scenarios where signal interference occurs between instruments and equipment during signal transmission in automated instrumentation, control systems, and actuation structures—leading to system instability and erratic data fluctuations. Also ideal for situations where signals from different devices or instruments need to be converted due to their varying characteristics. For example, when a single signal needs to be split into multiple channels to simultaneously feed different pieces of equipment. ⚪ Addressing loop interference caused by multi-point grounding. ⚪ Addressing electromagnetic interference and the intrusion of high-order harmonic signals. ⚪ System-side current/voltage output is sent to the field-mounted valve positioner. ⚪ Applicable on-site equipment: valve positioners, electrical converters
Suitable for measuring the pressure values of liquids, gases, or steam, integrating switch control, local display, and remote signal transmission functions. Key operation to set action values and action modes. The switch output is a passive dry contact signal (SPDT). Commonly used for: 1. Air compressor start-stop control; 2. Pipeline pressure high and low limit alarm, interlocking start-stop of pumps, etc. The pressure switch directly outputs switch signals, and its function can achieve the output switch control of a pressure transmitter + PLC/control instrument. This product has the following features:<br/>● Supports 330° rotation of the body<br/>● Multiple switch output<br/>● Local display of pressure values<br/>● Supports delayed alarm<br/>● Key setting of action values<br/>
Suitable for measuring the pressure of liquids, gases, or vapors in explosion-proof environments, this device allows local switching control for interlocking purposes, displays pressure values on-site, and can transmit signals remotely to the control system. Key operations enable users to set the actuation value and mode. The switch output is a passive dry-contact signal (SPDT). Common applications include: 1. Start/stop control for air compressors; 2. High- and low-pressure alarms in pipelines, triggering interlocked pump start/stop sequences, etc. The pressure switch directly outputs a switching signal, delivering functionality equivalent to that of a pressure transmitter combined with PLC/control instrumentation for switch-based control. This product features the following characteristics: <br/> ● Suitable for use in explosion-proof environments <br/> ●Multi-channel digital output <br/> ● Display pressure values directly on-site <br/> ● Multiple alarm methods can be set. <br/> ● Set action values with buttons <br/>
