YAMADEN – DB – 209

It has no moving parts and has a long service life. Stable level meter in a wide range. Liquid level measurement, powder surface measurement is possible.

To achieve a stable measurement with high sensitivity capacitance type level gauge

  • It not only responds to liquids, but it also corresponds stably to particle measurement.
  • Excellent linearity over a wide measurement range.
    · It corresponds to wide temperature drift.
    ■ Non-explosion-proof type is LB type.
    ■ Intrinsically safe type is DB type.

The sensor section corresponds to various electrodes such as rod electrodes and wire electrodes. In addition, intrinsically safe explosion-proof type is also available.

Features

The intrinsically safe explosion-proof structure is not limited to normal operation, of course, even when two accidents that compromise safety overlap, there is no overheating leading to an explosion, no matter where the hazardous location setting section shorts, The fact that the electric spark does not occur is a structure confirmed by an ignition test, etc. at public institutions.
Therefore, as long as wiring is made in compliance with the factory electrical equipment explosion proof needle 2500 (wiring of intrinsically safe circuit), no special pressure resistant case etc is required.

1. the sensor unit, the Zener barrier, each of the wiring between the power supply unit has adopted a two-wire.

2. high zeros accuracy with respect to the temperature change.

3. The amplifier is because it uses a cassette system, maintenance is easy.
