Digital hall effect teslameter - gaussmeter
The DTM-133 Digital Teslameter offers accurate, medium resolution measurement of magnetic flux densities at an economic price.
Features:
- Resolution of 1 part in 12,000
- 4 ranges
- Maximum field 3 Tesla
- 6 digit display (5 digit, plus sign)
- optional RS232 or IEEE488/GPIB communications.
- Accuracy is ± (0.03% of reading + 0.03% of full scale) with LPT-130 or MPT-132 probe.
- Temperature coefficient is 80 ppm / ° C when used with LPT-130, or 140 ppm / ° C when used with MPT-132 probe.
- Accuracy and temperature specifications include performance of probe.
- Because the probe characterisation information is stored in the probe assembly itself, any Group3 probe can be used with any Group3 DTM.
- Two buttons on the front panel are used to select the operation of the teslameter. The following modes can be selected for the display - magnetic field, peak hold of magnetic field, AC component of field.
- Digital filtering (time averaging) can be enabled to suppress short term fluctuations.
- Several teslameters with the serial communications option (up to 31) can be formed into a local communications loop, all of them talked to by the one serial port on the control computer. The system can be operated in a trigger mode, where the timing of the measurements by several teslameters can be synchronised
- Internal switches select serial data format, baud rate, device address, string terminators, filtering, gauss or tesla units, data format, service request action, EOI action, and reset system to defaults.
- An analog output is available. This is a buffered version of the raw probe signal, and is not corrected for linearity or temperature. It offers an instantaneous field value, (0 to 9kHz)
- All models are available without display or front buttons, for true "Black Box" requirements.
- Panel mount versions are available, and panels with correct cut-outs and mounting hardware.
- The operating temperature range of the probe and instrument is 0 to 50 ° C
