HS code：8517623990

Product Details：

Product Dimensions：

The 23747-04 is a pre-terminated, shielded cable featuring a specific length and connector configuration optimized for the Rosemount analytical product line. It serves as the vital link between the sensing element and the liquid analytical transmitter (such as the Rosemount 1056, 56, or 5081). The assembly typically includes specialized insulation to prevent signal leakage and a rugged outer jacket to resist chemical exposure and physical wear.

Product Parameters

Cable Length: This specific dash number (-04) typically corresponds to a length of 10 feet (approximately 3 meters).
Connector Type: It features a VP6 (Variopol) quick-disconnect connector on the sensor end. This is a multi-pin, waterproof connector that allows for rapid sensor replacement without re-wiring the entire run.
Configuration: 6-pin Variopol assembly designed for pH, ORP, and temperature compensation (RTD) signals.
Operating Temperature: Rated for standard industrial ranges, often up to 100°C (212°F) depending on the specific jacket material.
Signal Protection: Integrated shielding (drain wire) to minimize electromagnetic interference (EMI) and radio frequency interference (RFI).
Wire Gauge: Typically utilizes high-quality 24 AWG or 22 AWG conductors for signal stability.

Product Advantages

Quick Disconnect Capability: The Variopol connector eliminates the need to open the transmitter housing or disturb the permanent wiring when replacing a sensor, significantly reducing maintenance downtime.
Signal Integrity: Designed with high insulation resistance to handle the high-impedance output of pH glass electrodes, which prevents signal "drift" or measurement errors.
Waterproof Reliability: The VP connector is rated for submersion and high-moisture environments, ensuring a stable connection even in wet process areas.
Durable Construction: The outer jacket is specifically selected to withstand common industrial chemicals, oils, and UV exposure.
Simplified Troubleshooting: Using a standardized cable assembly makes it easier to isolate whether a measurement issue is caused by the sensor, the cable, or the analyzer.

Important Considerations

Dry Connections: While the connector is waterproof when mated, the internal pins must be kept completely dry and clean before connection. Any moisture or salt bridge inside the connector will result in erratic readings.
Cable Routing: Avoid routing this cable near high-voltage power lines or heavy motor leads to prevent electrical noise from distorting the sensitive analytical signal.
Minimum Bend Radius: Do not exceed the minimum bend radius during installation, as sharp kinks can damage the internal shielding and conductors.
Compatibility Check: Ensure the "VP6" connector matches the "VP" version on your sensor. There are different pin configurations (like VP8), and they are not cross-compatible.
Cable Length Limits: While longer cables are available, excessive length can increase signal noise. For distances beyond 15-20 feet, a pre-amplifier is often recommended.

Product Applications

The 23747-04 cable is widely used across industries where liquid quality monitoring is critical.

Water and Wastewater Treatment: Monitoring pH levels in influent and effluent streams to ensure environmental compliance.
Chemical Processing: Real-time pH or ORP measurement in reaction tanks or neutralizing systems where chemical resistance is required.
Power Generation: Monitoring boiler feed water and cooling water quality to prevent corrosion of expensive infrastructure.
Food and Beverage: Used in Clean-in-Place (CIP) systems to monitor the concentration of cleaning agents and final rinse water.
Pulp and Paper: Monitoring bleach plant operations and white water recovery systems.
