One Device, Dual Measurement: Simplifying Complexity
MD-S853TL Electronic Digital Display Integrated Temperature-Liquid Switch
In hydraulic stations and lubrication systems, monitoring both tank liquid level and oil temperature is a common requirement. Traditional solutions necessitate two separate instruments, leading to higher costs for installation, wiring, and maintenance. Furthermore, a single liquid level switch or temperature switch often fails to meet complex demands such as multi-point alarms, PLC interlocking, and analog signal acquisition. These harsh industrial environments—filled with oil, vapor, dust, and vibration—place extremely high demands on product protection and data stability.

 
To address this, MEOKON introduces the MD-S853TL, integrating liquid level and temperature monitoring into a single device. Featuring a stainless steel housing and a plastic head with an IP67 protection rating, it supports local display of both level and temperature. With 4 switch outputs and 2 analog 4-20mA outputs, it is perfectly suited for industrial sites like hydraulic systems, lubrication systems, and machine tool automation.

• Fulfills the Integrated Monitoring Need: Hydraulic stations, lubrication systems, and machine tool tanks often require simultaneous monitoring of low liquid levels and abnormal oil temperatures. An integrated product reduces the number of instruments and installation points.
• Enhances System Integration: The combination of 4 switch outputs and 2 analog 4-20mA outputs covers various interface requirements, including PLC alarms, analog acquisition, and interlocking control.
• Expands the S853 Series: Alongside the MD-S853 pressure switch and MD-S853T temperature switch, this new model offers a highly integrated option featuring “level display + temperature display + alarm settings + analog output.”

Making Data “Visible and Tangible
MD-S907P IoT Data Acquisition Terminal

In traditional industrial settings, the status of control cabinets is often a “black box,” leading to delayed responses and operational halts when failures occur. Issues like data gaps, monitoring blind spots, and lagging maintenance are common. The MD-S907P IoT Data Acquisition Terminal is designed to solve these pain points with highly efficient data monitoring capabilities.

1.Comprehensive Perception

With a rich array of input interfaces acting as the “nerve endings” of the industrial site, it achieves comprehensive, high-precision real-time data collection.

• 16-channel Digital Input: Includes 8 channels of AC220V powered inputs and 8 dry contact inputs, compatible with contactors and buttons to accurately monitor run, fault, and manual/auto statuses.
• 4-channel Analog Input: Supports standard 4-20mA industrial signals to accurately capture data from pressure, temperature, flow, and level sensors.

2. Wireless + Wired Redundancy: A dual-link transmission ensures data is reliably sent back even if the wireless network fluctuates or fails, creating an uninterrupted industrial-grade data highway.

• Wireless: Enables flexible deployment and rapid cloud connectivity, freeing you from wiring constraints.
• Wired (RS485): Provides a stable backup with strong anti-interference capabilities.

3. Compact Size, Powerful Core:

With dimensions of only 70×90×175mm, its compact body fits easily into standard distribution cabinets and PLC control boxes.
The high-strength, industrial-grade flame-retardant housing is dust-proof, moisture-proof, and impact-resistant, making it perfect for harsh industrial environments.
High-brightness LED indicators provide a clear view of power, operation, and communication status, simplifying on-site debugging and maintenance.
Directly supports AC220V industrial power supply, eliminating the need for extra power modules and simplifying wiring.
4. Plug-and-Play Deployment

The combination of DIN rail clips and phoenix-style terminals allows for rapid, tool-free installation and easy wiring, even in tight spaces.
5. Cloud-Enabled Intelligence

Paired with the Da Lan Mao (Big Lazy Cat) Equipment Health Management Cloud Platform, it supports remote status viewing, fault warnings, parameter debugging, and automatic report generation for predictive maintenance.
National Standard Compliance, Intelligent Fire Safety

MD-S908 Data Transmission Unit
As a critical safety feature in data centers, libraries, museums, airports, and train stations, the pressure status of gas fire extinguishing cylinders is paramount to the system’s reliability. The MD-S908 is a specialized data transmission unit developed by MEOKON for IoT monitoring of these systems, fully compliant with the GB25972-2024 standard for gas extinguishing systems.
