Guided Wave Radar Level Transmitter

Product Type: Guided Wave Radar (GWR) Level Transmitter — available in Rod-type and Cable-type probe configurations

Rigid Rod probe — Range up to 6 m
Flexible Cable probe (with weighted end) — Range up to 35 m

Housing: Dual-compartment cast metal housing with blue weatherproof cap, dual cable/conduit entries for wiring and display/terminal access

Process Connection: Flanged mounting (top-mounted, flange size per application)

Pressure Rating (PN): -0.1 to 40 MPa

Operating Temperature (O/T): -200 - 400℃

Accuracy: ±5 mm

Output Signal: 4-20mA, HART, Modbus/RS485

Explosion Protection: Exd (flameproof), Exia (intrinsically safe)

Dual Probe Options for Flexible Application: Rod probe for shorter, more rigid measurement points; cable probe with weight for long-range, high-vessel installations — covering everything from 0 up to 35 m.

Extreme Temperature & Pressure Capability: Rated to -200-400℃ and up to 40 MPa, suitable for cryogenic, high-temperature, and high-pressure process vessels.

High Accuracy & Reliable Interface Detection: ±5 mm accuracy ensures precise level and interface tracking even in turbulent or foam-prone media, unaffected by vapor, dust, or dielectric variation (unlike non-contact radar).

Flexible Digital Communication: Supports 4-20mA/HART as well as Modbus/RS485, enabling integration into both legacy analog loops and modern digital control systems.

Certified for Hazardous Areas: Dual explosion-proof certification (Exd/Exia) makes it suitable for classified zones in oil & gas, petrochemical, and chemical plants.

Ideal for level and interface measurement in high-pressure/high-temperature vessels, separators, storage tanks, and reactors across oil & gas, petrochemical, and chemical processing — including applications requiring cryogenic or superheated service, and interface detection between immiscible liquids (e.g., oil/water).
