Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Pressure transducers

High-accuracy M5100 and U5100 pressure transducers from Measurement Specialties are designed for harsh applications requiring long-term stability. Applications include process control, hydraulic and pneumatic systems, pumps, compressors, and agriculture equipment. The M5100, offered for gauge or sealed gauge sensing, features a rugged, vibration-resistant package suited for high-pressure, high cycle-count applications that can produce fatigue-related failure. The U5100 features an oil-filled stainless steel isolated capsule diaphragm to provide accuracy in applications of less than 150 psi (10 bar). Both transmitters have a CE rating, an application-specific integrated circuit for extended-range temperature compensation, signal conditioning, and output amplification. Various options for ports, connectors, and electrical outputs are available, and the temperature ranges from -20 to +85ºC (-4 to +185ºF), with extended performance to 125ºC (257ºF).
