*1:The sensitivity such as ±0.5 dB and ±1 dB represents sensitivity variation for each sensor ( individual difference), not the measurement accuracy. Performing calibration for each of the sensor according to its respective sensitivity value enables measuremet to be performed under the same conditions and with the same accuracy, irrespective of the sensor type. 1 G≒9.8 m/s2

For the water-resistance processing of NP-3331B / 3331N30
When NP-3331B/3331N30 are used in where the sensor may be splashed or spilled water, please refer to the procedure to handle
as follows. (Equivalent of IPX 7)
Attention:
Please make this modification at your own responsibility. The failures or troubles occurring through modification will be handled on a fee basis even during the warranty period. For modification (fare-paying service), contact your nearest distributor or our sales office nearby.
1) Attach the TNC plug of exclusive cable (NP-0140 series) to the sensor.
2) Apply entirely the silicon rubber adhesive (sealing agent) to the cable part where is put on a rubber cover of NP-0140, connector part and sensor part. • Recommended manufacturer of sealing agent: Shin-Etsu Chemical Co., Ltd
3) Shift the water-proof rubber cover to the specified position.
4) Harden the sealing agent adequately.
