Today I studied about autoclaves and SOP of the autoclave, So I thought to write small article what I learn from the SOPs for any person who would like to study.  Autoclave is a specialized equipment used to carry out industrial and scientific processes requiring elevated temperature and pressure in relation to ambient pressure temperature. Autoclaves are use in medical applications to perform sterilization.  PhotoLink: https://www.google.com/searchq=autoclave+machine&sxsrf=ALeKk015_0JI7icmpRvyoWOT7pO9ooi3RA:1588430738705&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjP47jPtZXpAhVQbysKHQfVBuUQ_AUoAXoECBMQAw&biw=1366&bih=610 Autoclave is use for  Cultures and stocks of infectious material,  Culture dishes and related devices,  Discarded live and attenuated vaccines,  Contaminated solid items such as: petri dishes, pipettes, gloves, paper towels,  lab coats, solid and liquid waste,  Items for sterilization such as: glassware, media, liquid solutions

Today I am planing to discuss about sensors used in BMS systems. In my work places used Dwyer sensors for the installation, So most of my explanations will based on this sensors. But there are lots of  sensor manufacturing companies around the world. As we understand previous article BMS system mainly control HVAC system in the building and most of the other services will monitor (Ex. Fire System, Plumbing System...etc.). First I discuss about sensors used in HVAC systems. Find Bellow mostly used sensors in HVAC systems, Temperature sensors  Outdoor Temp and RH sensor Flow switch Pressure Sensors Differential Pressure Sensor  CO2 sensor Static Pressure Sensor Flow Meter Temperature Sensors :  We use two type of sensors in the BMS system, one is duct type and other is immersion type sensors. Duct type mainly used to measure air temperature in air handling unit (AHU) and air ducts. Immersion type sensors use to measure water temperature in chilled water supply and c
