1 SERES REMOE SELS SRY RSMERS

2 ROUO he SR series is a complete line of diaphragm seals including threaded, flanged and sanitary designs. he seals are available in a wide selection of wetted materials meet various process requirements, but without being unnecessarily expensive. Standard diaphragm seals are available in models conforming S, and JS specifications. Other standards are also available on request, consult Smar for available options. wide variety of sizes and ratings are available for these standards. langed seals are available in dimensions up mm ( in) and ratings up bar ( psi). hreaded seals are available in sizes up ½ in rated at psi. he maximum process pressure depends on the seal rating and the maximum process temperature. he temperature limitation depends on the material and fill fluid chosen, and the minimum process pressure. Seals are available with fill fluids that can operate at temperatures as high as. he complete system of seal, capillary and transmitter is manufactured and assembled in Smar s own facry under our own complete control. he Smar SR line of remote seals is specially designed with a minimum diaphragm displacement be used with Smar electronic pressure transmitters. reat care has been taken in the design of the seals ensure that the seal affects the high accuracy associated with Smar electronic transmitters as little as possible. nother major design objective was adhere standards and recommended practices for process connection and seal construction. remote seal isolates the pressure transmitter from the process while still allowing the transmitter measure the pressure. he main application for a remote seal is as a protective device, however, it also enables a differential pressure transmitter be used for density measurement. he function of a remote seal is: o prevent the process fluid from entering the pressure transmitter thereby protecting the instrument if the process fluid is corrosive and would otherwise attack and destroy the transmitter. o prevent process fluids with very high temperature from coming in contact with and destroying or otherwise affecting the pressure sensor. o prevent abrasive process fluids from scratching the isolating diaphragm. his may happen if the process fluid is carrying suspended solids. o prevent the process fluid from building up or solidifying inside the transmitter and blocking the transmission of pressure the sensor. his may happen if the process fluid freezes, polymerizes or is carrying suspended solids, is viscous or crystallizing. Sanitary seals are used prevent bacteria etc. build up in cavities in the transmitter. hese seals are designed be easily cleaned. hese are required in the pharmaceutical and food & beverage industries. he remote seal is connected the transmitter via an armored capillary. properly installed remote seal hydraulically transmits the process pressure the sensor of the pressure transmitter through the liquid filled capillary. he capillary is very thin and the transmitters are fitted with a special seal connection with a very small volume keep the amount of fill fluid at a minimum.

3 EERL PPLO OSEROS void these common mistakes: Wetted materials not compatible with the process fluid. onsider normal operation as well as cleaning. ill fluid not compatible with the process fluid may cause hazardous situations in case of diaphragm ruptures and the fluids come in contact with each other. or some process fluids only a certain fill fluid may be used, but that fill fluid may be incompatible with other materials that may be present in piping etc. Other considerations are the food and drug industries where even mildly poisonous fill fluids cannot be used. Vacuum below mmg requires special considerations. Operation at these high vacuums is possible if done right. onsult Smar for advice. Process data such as pressure, temperature, required seal type and process fluid must be furnished evaluate the application. Only one seal or capillaries with different lengths on a differential pressure transmitter causes zero shift as the temperature changes. Long capillaries cause response time increase and augments temperature effect. he temperature is beyond the upper or lower operating temperature range of the fill fluid. he process pressure exceeds the seal pressure rating at maximum process temperature. he pressure rating for seals decreases with rising temperature and may under certain conditions be lower than the nominal rating. Upper measurement ranges below mm O will see errors as the remote seal reduces the sensitivity of the transmitter. OE : he user must insure that the right type of seal with the proper fill fluid and wetted materials is used, and if a remote seal should be used at all. OE : ill luid onsiderations efore a fill fluid is chosen, it must be determined that it is suitable for operation at the extremes of vacuum and temperature at which it will operate. nother important consideration is that the diaphragm may be damaged. t is therefore important that the fill fluid does not start a hazardous chemical reaction with the process fluid. s a rule of thumb, do not use hydrocarbon based fill fluids, such as silicone, with strong oxidizers like: chlorine, hydrogen, hydrazine, oxygen, peroxide or nitric acid. lso do not use luorolube oil if there is a chance for it come in contact with aluminium or magnesium. Special fill fluids are available. Vacuum onsiderations he fill fluid vapor pressure point is dependent on temperature. t a combination of high temperature and pressure near vacuum the fill fluid may vaporize and the pressure measurement becomes inaccurate. he seal may also become permanently destroyed. areful selection of fill fluid is therefore of up most importance. he SR series offers four standard fill fluids. rief data is given in table. or more data, e.g., vapor pressure curves, and fill fluids for special requirements, please contact Smar. See our SR manual for temperature errors and response time calculations.
