Status Instruments claims a first for its new MAA type temperature transmitter
23 November 2010
Status Instruments' new HTR integrated head temperature transmitter is believed to be the first complete transmitter that fits into the miniature MAA connection head. Due to space constraints, the head is usually only used with a connection block, requiring the transmitter to be mounted some distance away from the sensor.
Status has pioneered miniature electronic design for its transmitters, without sacrificing the functionality of larger standard devices that would normally require more spacious KNE type heads. The HTR can be used with RTD, slide-wire and resistance inputs. The standard product has over 30 resistance sensors to choose from, including Pt100, Pt500, Pt1000, Ni100 and Ni1000.
Designed to meet the needs of both industrial and HVAC applications, the 3 wire voltage output version can be programmed to output any value between 0 and 10Vdc. For example, the product can be configured to accept Pt1000 sensors and provide a 0 to 10Vdc output direct from the head – ideal for HVAC applications.
To optimise the use of the built-in memory, application specific sensor linearisation correction data is loaded into the transmitter during user configuration, rather than being permanently stored in the unit. This means the design uses a microprocessor with a smaller memory and therefore contributes to a lower cost product.
Configuration is carried out quickly and easily via PC or laptop, using Status’ new USB configurator. Configuration can be saved as a file for future use and additionally the user can read live process data when connected to a PC.
