Offer > T,R,ΔV transmitters > T1545
The temperature transmitter is fully programmable - both sensor type (RTD or thermo-couple) and temperature range may be redefined at any time. Transmitter may also be configured to measure voltage or resistance. User-friendly configuration software runs under Windows - all that is needed is a low-cost adapter (see below) connected between PC's RS232 serial or USB port and programming port of the transmitter. Separate power supply is not required. The input is constantly monitored during configuration and the user has additionally an option of adjusting transmitter's zero and gain (within ±2%) to a specific sensor. Output current may be set independently from input for testing purposes. Nine standard thermocouple types are implemented. Non-standard sensor may be defined with a temperature versus signal table prepared under any text editor. Linearization and internal CJC are provided and may be switched on and off.
Externally, the T1545 does not differ from a conventional analog transmitter, but, apart from configuration possibilities, it offers some additional advantages in signal filtering and accuracy. For example, a 'spurious noise' filter allows to remove from signal non-symmetric spikes of large amplitude, which would otherwise distort the output even if long averaging times were used. The averaging signal filter, in turn, has an 'intelligent' option of quick adaptation to faster signal changes while preserving long integration time constant for slowly changing signal.
As mentioned earlier, T1500 series transmitters need an adapter for connection with a PC. To connect to RS232 port one needs T1501 adapter, and for USB port connection either T1505 or T1506 should be used. Configuration code, working under Windows and named "T1500.exe", is available for download at Accessories & programs page where the adapters are presented as well.
