detection is the process of identifying potentially hazardous gas leaks by means of various sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor‚ Ultrasonic gas detectors‚ electrochemical gas detectors‚ and Semiconductor Sensors. More recently‚ infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications‚ and can be found in industrial plants‚ refineries

IEEE SENSORS JOURNAL‚ VOL. 6‚ NO. 3‚ JUNE 2006 631 Magnetic Sensors and Their Applications James Lenz and Alan S. Edelstein Abstract—Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include

A 62-year old diabetic black man presents in the emergency room with a swollen left leg with areas of blanching and blue mottling. A "foul odor" is coming from a dressed wound. The physicians remove the dressing and a brownish fluid is seeping from a wounded area. The fluid contains what appear to be small bits of the tissue. No pus appears to be present. The wound has a strong "rotten" odor. Five days earlier‚ while at his work as a farmer‚ he caught the leg in his manure spreader‚ sustaining a

How Ultrasonic proximity sensor works An ultrasonic proximity sensor uses a piezoelectric transducer to send and detect sound waves. Transducer generate high frequency sound waves and evaluate the echo by the detector which is received back after reflecting off the target. Sensors calculate the time interval between sending the signal and receiving the echo to determine the distance to the target. When the target enters the operating range the output switches. The ultrasonic proximity switches are

RANGE: 20-80cm VOLTAGE OUTPUT: 1V-15V TEMPERATURE: -10°C to 60°C The sensors that have been chosen have a distance range around 10cm – 80cm where the sensors only works around that range. The size of the sensors also should be consider due it will fluency the size of pipe. If the cable
