2-wire transmitter RF Admittance, the process used to detect all media, from low dielectric constant (such as refined) products to conductive mud, and even viscous media materials. Standard two-wire technology and electronic control system is fully compatible, easy to install wiring. After 85 years of technology development, our company's products have been more perfect. Advanced electronic circuit design for the instrument provides a high precision, high stability and high anti-jamming capabilities, while self-diagnostic circuitry to ensure the normal operation of the system.
