The K-TEK M4A-AT Level Control Transmitter is a magnetostrictive level measurement device designed for continuous, 

high-accuracy fluid level sensing in industrial environments. It uses magnetic float and magnetostrictive sensing technology 

to deliver precise and reliable real-time measurement of liquid levels in tanks, vessels, and process containers. This 

M4A-AT transmitter is built to withstand harsh conditions, including wide temperature ranges, corrosive media, and 

heavy industrial use, making it ideal for industries such as oil & gas, chemical processing, water & wastewater treatment, 

and power generation. The robust design offers low maintenance and integration with control systems via standard 

output signals like 4–20 mA or Modbus/RTU for process control and monitoring applications.

Frequently asked questions：

Q1: What is the K-TEK M4A-AT Level Control Transmitter?
A: The K-TEK M4A-AT is a magnetostrictive liquid level transmitter designed to provide continuous, 

high-precision measurement of fluid levels in tanks and industrial vessels.
Q2: What output signal does the K-TEK M4A-AT provide?
A: The transmitter typically provides a standard 4–20 mA analog output, and some versions can support digital 

communication protocols such as Modbus RTU.
Q3: What is the measurement principle of the K-TEK M4A-AT?
A: The device uses magnetostrictive sensing technology combined with a magnetic float to detect the exact position 

of the liquid level with high accuracy and stability.
Q4: What power supply is required for the K-TEK M4A-AT?
A: The K-TEK M4A-AT normally operates on a 12–24 V DC power supply, which is standard for most industrial 

control systems.
