Technical Information Omnigrad T0, T Temperature Measuring Technology Terminal heads for mounting on thermowells of resistance thermometers and thermocouples Function and system design ll terminal heads can be screwed onto thermowells or extension necks of resistance thermometers and thermocouples. They are used to protect the integrated connection socket or head transmitter. wide range of terminal heads for practically all kinds of applications in process measuring technology is available. For offshore or petrochemical plants in hazardous areas or for the food and pharmaceutical industry with stainless steel versions. ll the terminal heads have a cable entry with a seal. The metal E+H terminal heads are fitted with seals for temperatures up to 00 C ( F). If a head transmitter or a display unit is present, the maximum ambient temperature of the terminal head is restricted by the maximum ambient temperature value of the head transmitter or the display. table illustrates the possible combinations of the terminal heads with E+H transmitters. diagram shows the connection between the process temperature and thermometer length.

Omnigrad T0, T Function and system design Measuring principle Omnigrad T0, T0, T0D, T0R, T0W, TE, TH: The terminal heads are housings with a high protection class (IP) suitable for temperature measurement. ll the temperature transmitters of the itemp family TMT8x (analog, HRT, PROFIUS P ) can be incorporated in them. The housings can be fitted on top of an Omnigrad M as a terminal head for RTD or TC temperature sensors, or used as a junction housing in a remote application. The T0R and T0J terminal heads meet all the hygiene requirements of the food and pharmaceutical industry. Different electrical connections can be supplied: M0x., PROFIUS P plug connector, ½" NPT+ Skintop etc. Omnigrad T0J: The T0J housing allows local visualization of the current value of the to 0 m loop current in physical units. The optional -wire LCD digital display is usually connected in series with a -wire temperature headmounted transmitter and both are installed into the stainless steel housing. The T0J is a stainless steel housing (ISI 6L or DIN.0) with a high protection class IP66/IP67, suitable for temperature measurement applications. The T0J can contain any temperature transmitters of the itemp family TMT8x (analog, HRT, PROFIUS P ) and/or a loop-powered -digit LCD display. The T0J housing is available with or without a viewing window and can either be mounted on a pipe with special brackets or fitted on top of an Omnigrad M-type temperature sensor. T0J display and user interface The LCD display uses a series connection to the to 0 m -wire loop and is powered through a little voltage drop. y means of keys, it is possible to modify the configuration: zero point and span, decimal places, filter on the reading, measurement resolution and selection of the over-range functionality. With the same keys it is possible to execute the calibration of the /D converter. ll configuration parameters are stored in a nonvolatile EEPROM. The display is mounted in the T0J stainless steel, window-based housing by means of three screws on the top cover. The loop-powered -digit LCD display allows the direct display of the temperature values in engineering units C or F. The EMC properties correspond to EN 6000-6- and EN 6000-6-.

Head heating in C Omnigrad T0, T Temperature increase in terminal head The following diagram illustrates the increase in temperature (reference values) for two process temperatures in the terminal head over the ambient temperature depending on the length of the thermometer extension neck. Thus, the length of the extension neck must be selected in such a way that the temperature in the head is within the limit values specified in the "Mechanical construction and ordering information" section to prevent the terminal head from overheating. 0 0 0 0 0 7 00 0 7 00 Neck extension length in mm 0 C 0 C Process temperature Electronic head transmitter The required type of output signal can be obtained by choosing the correct head mounted transmitter.
