Sensor and Model
Description
Applications
MT801/MR801
Long range transmitting / receiving sensors with 10db gain home antennas Maximum range 100 in air. NEMA 4x enclosures, MT801/MR801 temperature range: -20°F to +140°F (-30°C to +60°C). Standard Service Vehicle detection, railroad car detection & positioning. Liquid level control, bin level control (sand, rock, asphalt, coal, cement, fly ash, etc.) Use with Part #41121 window.
MT811/MR811
Short range accurate high/low level detection. Range up to 10 in air. Used primarily for accurate position and level sensing of bottles, small boxes, etc. NEMA 12 enclosures. chute Temperatures range: -20°F to +140°F (-30°C to +60° High/low level detection, empty bottle detection, battery filling level control, empty box detection counting, short range plugged chute.
MT841/MR841
Similar to MT811/MR811 except 10 db gain horn antennas are used. Designed to be used in Part No. 41105-X, waveguide extension kit. Maximum range 100 in air, Enclosures is NEMA 12. When used with 41105-X, maximum temperature at antenna is 600°F (313°C). Amplifier maximum temperature is 140°F (60°C) Waveguide with 10 db gain horn antenna. Level control when vessel or environment is extremely hot. Furnaces, kilns, cupolas, fly ash, furnace fluidized beds, etc. Use with Part #41121, #41213 and with castable refractory materials.
MT851/MR851
Identical to MT801/MR801 except sensors are constructed in 2 1/2” steel pipe. Designed to be screwed directly into steel vessels using 2 1/2” weldment (P/N41249-order separately). Window material is FDA approved UHMW polyethylene 1” thick. Contact factory for other available material. Temperature range: -20°F to +140°F (-30°C to +60°C). Severe service. Bin level control of sand, rock, asphalt, coal, etc. In areas where physical abuse of sensor is possible. Rugged.
MT861/MR861
Similar to MT851 and MR851 except waveguide 10db horn and electronics is located inside water cooled jacket. Hot product, water cooled Level control of limestone, ores and other products contained in firebrick enclosures.
