Core Advantages and Technical Highlights

The Panametrics VeriDri 417068-N moisture transmitter delivers significant advantages, making it a preferred choice for OEMs and industrial users seeking reliable and precise moisture measurement. Its design focuses on blending high performance with practical considerations for diverse applications.

Accuracy and Wide Measurement Range: The paramount advantage of the VeriDri 417068-N is its exceptional accuracy, offering a calibrated accuracy of ±2°C from -65°C to 10°C dew/frost point. This is coupled with a broad overall moisture measurement capability spanning -110°C to 20°C dew/frost point or 0 to 10,000 PPMv. This wide range and precision enable the Panametrics VeriDri 417068-N to reliably monitor moisture across various critical processes, from very dry conditions in desiccant dryers to higher moisture levels, ensuring optimal process control and product quality.

Advanced Sensor Technology: At the heart of the VeriDri 417068-N is Panametrics’ proven thin-film aluminum oxide moisture sensor technology. This sensor is renowned for its superior sensitivity, rapid response time (less than five seconds for 63% step change), and long-term calibration stability. Each sensor within the Panametrics VeriDri 417068-N is individually computer-calibrated and traceable to NIST standards, guaranteeing measurement reliability and compliance with stringent quality requirements.

Robust and Compact Design: The 417068-N features a rugged construction with a Type 4X/IP67 environmental rating, allowing it to withstand harsh industrial conditions including dust, moisture, and temperature variations. Its compact size facilitates direct installation into process streams or in small sample systems, making the Panametrics VeriDri 417068-N highly adaptable for OEM integration where space is often at a premium. This durable and small footprint contributes to lower installation costs and greater flexibility.

Loop-Powered 4-20 mA Output: The VeriDri 417068-N simplifies wiring and system integration by being a loop-powered device, requiring only two wires for both power and signal transmission (4-20 mA output). This feature reduces cabling complexity, minimizes installation time, and lowers overall system costs, making the Panametrics VeriDri 417068-N an economical choice for new designs and retrofits. The 0.01 mA output resolution ensures precise signal transmission to control systems.

Fast Warm-up and Response: With a warm-up time of just three minutes to meet specified accuracy, the 417068-N provides quick operational readiness. Its fast response time to changes in moisture content further enhances process control, allowing for prompt adjustments and efficient management of drying cycles. The combined features of the Panametrics VeriDri 417068-N make it a high-value solution for continuous, real-time moisture monitoring.

Typical Application Scenarios

The Panametrics VeriDri 417068-N moisture transmitter is designed for a broad spectrum of industrial applications where precise and reliable moisture measurement in gases or non-aqueous liquids is critical for process efficiency, product quality, and equipment protection.

In regenerative desiccant air or gas dryers, the VeriDri 417068-N plays a crucial role in optimizing the regeneration cycle. By continuously monitoring the outlet moisture content, the dryer can initiate desiccant bed regeneration only when necessary, rather than on a fixed timed cycle. This demand-based regeneration, facilitated by the Panametrics VeriDri 417068-N, leads to significant energy savings and extends the life of the desiccant material, directly impacting operational costs.

For plastic drying applications, particularly in the plastics manufacturing industry, the VeriDri 417068-N ensures that polymer pellets are adequately dried before processing. Excess moisture can lead to product defects, such as brittleness or bubbles. The continuous monitoring by the Panametrics VeriDri 417068-N helps maintain optimal moisture levels, resulting in higher quality finished products and reduced scrap rates.

In medical air dryers and other critical clean gas systems (e.g., in pharmaceutical manufacturing or hospitals), maintaining extremely low moisture levels is essential for patient safety and process integrity. The Panametrics VeriDri 417068-N provides the precise measurement needed to ensure that compressed medical air meets stringent dryness standards, preventing condensation and microbial growth within distribution systems.

Furthermore, the VeriDri 417068-N is highly valuable in glove box monitoring for controlled atmosphere environments, such as those used in semiconductor manufacturing, battery production, or research laboratories where inert atmospheres (e.g., nitrogen or argon) are critical. Accurate moisture measurement by the Panametrics VeriDri 417068-N ensures that the glove box environment remains within specified dryness limits, protecting sensitive materials and processes from contamination. Its compact size allows for easy integration into such specialized equipment.

Installation, Commissioning and Maintenance Instructions

Installation Preparation: Before installing the Panametrics VeriDri 417068-N, ensure the process line is de-pressurized and isolated to prevent injury or damage. Select an installation point that provides a representative sample of the gas or liquid to be measured, preferably downstream of any filters or dryers. Ensure the ambient temperature and pressure at the installation site are within the specified operating ranges for the VeriDri 417068-N. Use appropriate tools for threading the transmitter into the process connection (3/4 inch-16 straight male thread with O-ring, or G 1/2 in with adapter if required), ensuring a leak-free seal. For electrical connections, use shielded twisted-pair cable for the 4-20 mA loop, ensuring the power supply is within the 7 to 28 VDC range. Adhere to all local electrical codes and safety standards.

Commissioning: Once the Panametrics VeriDri 417068-N is physically installed and wired, commissioning involves applying power and verifying operation. Power the loop from a suitable DC power supply. The VeriDri 417068-N will begin its warm-up cycle, typically achieving specified accuracy within three minutes. Monitor the 4-20 mA output signal using a multimeter or a connected control system (PLC/DCS/SCADA) to ensure it is within the expected range for the measured moisture level. If possible, compare the reading from the Panametrics VeriDri 417068-N with a known reference or another calibrated moisture instrument to confirm accuracy. For PPMv measurements, ensure the constant pressure provided at the time of order placement matches the actual operating pressure. No field calibration is typically required, as the VeriDri 417068-N is factory-calibrated and NIST traceable.

Maintenance Suggestions: To ensure the long-term accuracy and performance of the Panametrics VeriDri 417068-N, regular maintenance is recommended. The primary maintenance item is periodic recalibration of the sensor probe. Panametrics recommends factory sensor recalibration every six to twelve months, depending on the application and the environment’s severity. When not in use, store the probe with its plastic cover and desiccant packet threaded onto the probe to protect the sensor element. Inspect the VeriDri 417068-N and its connections for any signs of physical damage, corrosion, or contamination. Ensure the sample connection remains clean and free of particulate matter. For troubleshooting, verify power supply, wiring integrity, and ensure the process conditions are within the Panametrics VeriDri 417068-N‘s operating specifications. Avoid exposing the sensor to high concentrations of corrosive gases or liquid water, which can damage the aluminum oxide element.
