HART’s multidrop protocol allows one WirelessHART adapter to be connected to up to four measurement devices. The iTemp TMT82 temperature transmitter, a multi-channel input device has the capability to receive up to eight readings from a single such adapter. The cost of transmitters can be halved by using dual input temperature transmitters and the cost of installation could be reduced by over 50% with WirelessHART.
Endress+Hauser multipoint technology
Multipoint thermometers are the ideal solution when multiple measuring points are required within a process and the number of individual measuring points exceeds the point at which they are economically viable. They are also used when the physical design of the vessel or chamber does not allow for the required number of process connections. The multipoint can be manufactured with thermocouple or resistance temperature detector elements. These can also be converted to a common process signal (e.g. 4-20 mA, HART, Profibus or Foundation Fieldbus) using the innovative iTEMP temperature transmitter. This arrangement is most commonly used in applications such as silo temperature measurement for food and beverage, fractional distillation vessels and chemical storage tanks.
Over many years Endress+Hauser has re-evaluated conventional thoughts on multipoint sensor design, meeting the ever-increasing application demands that traditional assemblies are unable to cope with. Both rigid and flexible multipoint systems can be designed and manufactured with careful consideration of the end user’s specific requirements:
* Single-piece rigid stem for strength to prevent build-up of process media and to provide a smooth finish for hygienic applications.
* Inner guide tubes to enable fast, easy removal of temperature sensors for calibration or replacement.
* Dual input TMT82 temperature transmitters connected to a wireless adapter enabling eight measuring points to be transmitted through one wireless adapter.
* Temperature sensor guide tubes are welded in contact with the outer wall of the thermowell for fast response.
With many years’ experience of designing and manufacturing multipoint temperature sensors, Endress+Hauser can provide solutions for all applications.
