Omron ZN-THX11-SA Thermo-Humidity Logger

Description

The Omron ZN-THX11-SA is a dedicated station device engineered for industrial environmental monitoring and logging. It functions alongside an external sensor head to record and track atmospheric temperature and relative humidity parameters across critical production zones, cleanrooms, and warehouse storage locations. The device utilizes a front-panel digital display to provide immediate visual confirmation of localized parameters while running real-time processing calculations on the incoming sensor feedback. Collected records are stored locally in internal memory or written directly to removable solid-state storage media. Compatible with standard external power arrangements and secondary backup battery power options, it guarantees continuous data acquisition safety for delicate pharmaceutical, electronics, and food-processing applications.

Features

• Seamless plug-and-play synchronization with specialized thermo-humidity sensor heads.
• Dual-step 5-digit digital display for simultaneous parameter or status review.
• Multi-tier hardware measurement intervals ranging from seconds up to hourly tracking.
• Dual operating modes enabling system optimization for active reporting or low-power storage tracking.
• Removable memory card interface support for secure offline data backup and configuration deployment.
• Integrated alarm output port infrastructure for direct linking to auxiliary warning devices.

Applications

• Semiconductor production facilities and cleanroom climate verification.
• Pharmaceutical distribution warehouses and climate-controlled storage areas.
• Food and beverage manufacturing facility temperature and humidity auditing.
• Server rooms and critical data center environmental management.
• Calibration laboratories and precision testing environment monitoring.

Installation Guidelines

• Mounting Setup: Position the logger unit away from surfaces subjected to severe vibration or mechanical shocks. Ensure the front panel remains clearly scannable for engineering personnel.
• Cable Strain Relief: Clip the included ferrite core onto the incoming DC lines near the connection jack to minimize electromagnetic interference (EMI/RFI) on sensitive sensor readouts.
• Sensor Routing: Keep the connection cable linking the logger base to the thermo-humidity sensor head separate from heavy power cables, motor switchboards, or high-current transmission lines.
• Moisture Protection: The station unit body is rated for up to 85% relative humidity; it must be shielded from direct fluid exposure, splashing water, or condensing atmospheres.
• Battery Handling: When utilizing the device on battery-only mode, deploy nickel-metal hydride (NiMH) cells and set the device logic to sleep mode to sustain standard long-term sampling runs.

FAQ

• Which external probe is compatible with this environmental tracking base?
• It connects directly to the Omron Thermo-Humidity Sensor Head series designated as ZN-THS@@-S.
• Can the logging data be retrieved without interrupting live system power?
• Yes, data files written to the removable SD card can be retrieved according to standard field maintenance protocols.
• What is the maximum number of recording entries available within the built-in storage?
• The integrated internal memory space can hold approximately 8,500 independent data points before requiring data extraction.
• What type of SD card is recommended by the factory for standard applications?
• The recommended factory part number for system verification is the OMRON HMC-SD291 solid-state media card.
• How are the max, min, and average parameter metrics retrieved?
• The mathematical function configuration lets you toggle through instantaneous values, maximums, minimums, and averages on the front LCD screen.
• Is an external transformer or adapter packed alongside the main logging module?
• The package includes a straight-type DC cable, alarm connector, instruction literature, and utility software disk. Direct AC adapter selection varies by regional requirements.
• Can this logger run continuously for months without line power access?
• Yes, it can run for approximately 1 year on 2 AAA NiMH batteries when utilizing sleep mode settings with a 10-minute measurement interval and the SD card omitted.
• What action should be taken if condensation forms within the sensing room?
• The station operates strictly down to 20% and up to 85% relative humidity without condensation. If moisture builds up, isolate power and let the system dry entirely.
• What information is displayed via the two-tier screen layout?
• The 7-segment 5-digit dual display lets operators simultaneously review multi-variable logs such as temperature alongside humidity readouts.
• How often does the station scan the environment for parameter updates?
• The execution cycle is adjustable, providing engineering steps of 10s, 20s, 30s, 1 min, 2 min, 5 min, 10 min, 20 min, 30 min, up to 1 hour.
