SynC · Topic
These are the standards in the SynC Standards library that cover Sensors. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Factory-fabricated air terminal units that meter primary air from a central air system into an individual thermal zone in commercial, institutional, healthcare, and industrial buildings. Covers single-duct, dual-duct, and bypass metering arrangements; variable-volume and constant-volume airflow control; pressure-independent and pressure-dependent control basis; parallel and series fan sections; hot water, steam, and electric reheat with their valves, actuators, and safety devices; casing construction and acoustic treatment; primary damper and actuator; primary airflow sensing; radiated and discharge sound; the zone controller, zone sensor, and building automation interface; factory testing; installation; and field airflow, functional, and acoustic verification.
Online (continuous) water-quality and process analytical instrumentation for water and wastewater treatment plants and for industrial process applications. Covers the common measured parameters and their measurement technology — pH and ORP, turbidity (per USEPA Method 180.1 and ISO 7027), free and total chlorine residual, dissolved oxygen (DO), and conductivity — and addresses additional process analyzers (ammonia, nitrate, ozone, total organic carbon, suspended solids, streaming current) as applicable. Addresses sensor technology selection, sample conditioning and sample panels, in-situ (insertion/submersible) versus flow-through (grab/loop) mounting, calibration frequency and reference standards/buffers/reagents, automatic temperature compensation, reagent handling, maintenance and washdown access, signal output (4-20 mA / HART and digital protocols), and the compliance-monitoring (regulatory reporting) role where the analyzer serves as a reportable instrument. Loop integration, alarming, and data historization are covered in Control Systems Integration and SCADA And HMI Systems.
