·
Temperature range for instrument and probe
0 to 50° C
·
Best use in conjunction with an
MPT-141
or
LPT-141
for standard sensitivity or an
MPT-231
or
LPT-231
Hall Effect Probes for high sensitivity, low-field operation.
FEATURES
·
Because the probe characterisation information is stored in the probe assembly itself, any Group3 probe can be used with any Group3 DTM. However for full accuracy the DTM-151 should be used with a probe that has temperature compensation circuitry.
·
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, probe temperature.
·
Digital filtering (time averaging) can be enabled to suppress short term fluctuations.
·
Several teslameters (up to 31) with serial communications 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.
·
Two analog outputs are available. These are a buffered version of the raw probe signal, and are not corrected for linearity or temperature.
·
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 following specifications refer to DTM-151 with LPT-141 probe (standard size probe).
DTM-151 WITH LPT-141 PROBE (LIMPET PROBE)
Product Description
The LPT-231 is a high sensitivity, temperature-compensated Hall effect Probe designed to work with a DTM-151 or a DTM-152 Digital Teslameter. It operates on 4 ranges ; 0.03, 0.06, 0.12 and 0.3 Tesla. Probe cable can be customize to suit specific applications and can be up to 30 meters long. Probe orientation is transverse, reads positive when field vector enters top aluminium surface.
Four ranges, selectable from front panel:
1. 0.3
2. 0.6
3. 1.2
4. 3.0    tesla full scale
Note: Resolution depends on the range selected, and whether the digital filtering is enabled.
Note: Resolution available at the serial/GPIB port is greater than that of the display.
