The PIDMaxWell Stainless Steel Thermowell is the ideal protection solution for your temperature sensors. Manufactured from premium SS304, SS316, or SS316L, it is designed to withstand harsh, high-pressure, and corrosive industrial environments. Featuring a practical dual-thread design, the outer thread (1/2" NPT, BSP, or G) ensures secure pipeline mounting, while the inner thread allows for easy sensor insertion, replacement, and calibration without system shutdown. Both the stem diameter and insertion length are fully customizable to perfectly match your specific PT100 or thermocouple applications.  

The Maxwell SCR-7 Series is an advanced, three-phase intelligent digital power regulator designed for precise and reliable control of resistive heating loads in industrial applications. Engineered with a fully integrated design, it combines the SCR module, high-efficiency heatsink, and cooling fans into a single, compact unit. The SCR-7 series features a comprehensive digital display for real-time monitoring of output ratio, temperature alarms, and phase status. With support for multiple analog input signals (including 4-20mA, 0-10VDC, and 0-5VDC) and optional RS-485 Modbus RTU communication, it seamlessly integrates into modern PLC and automated control systems. Built-in protective features such as soft start, auto phase detection, and over-temperature alarms ensure maximum safety and longevity for both the regulator and the connected load.
