DIAPHRAGM TYPE BIN MONITOR (Series BLS 301M)
Jayashree Diaphragm Type Bin Monitor offers economical, reliable and durable point level controls for point level detection of dry bulk materials. The units can be used to eliminate bin overflow, maintain a pre-determined material level, indicate plugging of chutes or conveyors or provide any of a number of level control function. The flush mount, non-intrusive units are ideally suited when vessel size or internal clearance is limited or where protrusion into a vessel is not acceptable. All installation and servicing, including diaphragm replacement and sensitivity adjustment can be done from outside the vessel.

RF POINT LEVEL SENSOR DISK TYPE (Series SW 6201)
The RF Point Level Sensor is a most rugged and proven sensor for monitoring level in a chute. This is very useful for monitoring chute blockage. It is a special heavy duty disk / flange mounted probe. The probe senses only the steady level of coal lumps and does not actuate due to falling material dust or humidity. The effect of cable capacitance and drift with temperature is eliminated by using a driven shield arrangement. The controller unit operates an output relay when the coal level reaches near the sensor face. The probes are available for working temp. up to 200°C. Probes of different types are available for specific application like telescopic, Teflon coated etc..

ULTRASONIC LEVEL SENSOR (Series SW 3051)
The Ultrasonic level sensors of the Series SW 3051 are very useful for sensing high levels (up to 20 meters.) of liquids or slurry material. The sensor gives a 4-20 mA output signal to the controller and operates relays at preset high and low levels. Probes are available forsensing water levels of 5/10/15/20 meters.
