Conformal coating applied as standard

Coating is not only resistant to accidental exposure to corrosive gas or oily smoke, but has a number of benefits contributing to long-term reliability. It avoids direct exposure to air to protect printed circuit boards and electronic parts against humidity, moisture, dust, chemicals, and thermal stress, thereby preventing corrosion, migration and any other damages. (HumiSeal® 1A27NSLU is used as a conformal coating. )

Ceramic capacitors employed

The MS3000 Series employs ceramic capacitors to achieve low current draw with extremely low heat generation, thus leading to long service life.
(The ceramic capacitors are not affected by prolonged use, as opposed to aluminum electrolytic capacitors.)*2

Multi-turn trimmers employed

This series employs multi-turn trimmers for zero and span adjustments. Our conventional series have used 3-turn or 4-turn trimmers, but the multi-turn trimmers employed facilitate fine adjustment and provide improved resistance to vibration. The new trimmers also have static protection.

Distributor provided with a transmitter power supply switch

The distributor has a transmitter power supply switch on its front panel. Turning this switch off allows the distributor to be used as an isolator for adjustment. If you have not yet decided whether to use a distributor or an isolator at the design phase, you should select this model so that it can be used for both applications.*3

*2 DC powered: No aluminum electrolytic capacitors or tantalum capacitors used.
AC powered: Aluminum electrolytic capacitors are partly used in the power section.
*3 Note that the terminal connections are different depending on whether the unit is used as a distributor or an isolator.
