    Description

    Frequency meter 45D1-Hz is a mechanical indicator meter that measures frequency. There are many types of frequency meters, including electric systems, ferromagnetic electric systems, and inverter-type frequency meters that are rectifiers. Most of the installed frequency meters used to monitor the frequency at the production site use ferromagnetic electric meter measuring mechanisms.

    1 Measurement range: 30.00 ~ 99.99Hz (meters outside this range can be customized according to special specifications)

    2 Accuracy: ± 0.1Hz

    3 Display resolution: 0.01Hz

    4 Sampling rate: about 3 times / s

    5 Input signal type: Alternating voltage or unipolar pulse

    6 Input signal amplitude: AC10V ~ 500V

    7 Input loop power consumption: <1VA

    8 auxiliary power consumption: <3VA

    10 Overflow indication: display characters "HHHH" or "LLLL"

    11 Prompt message when no signal is input: display character "----"

    12 Alarm output: Alarm output: Upper and lower limit alarms are the same relay output, and the contact capacity is AC250V / 2A, DC30V / 2A.

    13 Transmission output: can be freely set to DC0 ~ 10mA, 0 ~ 20mA or 4 ~ 20mA, accuracy ± 0.5% FS, and electrical isolation between signal input and auxiliary power

    14 Transmission output load resistance: ≤ 500Ω

    15 communication interface: RS485 serial communication, using MODBUS_RTU communication protocol

    16 Environment: Non-corrosive occasions with temperature -10 ~ 50 ℃ and humidity ≤85% RH

    1. Purpose:

    The instrument is embedded and protruding installed on ships, locomotives, power stations, mines, metallurgy, petrochemicals or other mobile power equipment, and measures the frequency in the network at 50, 400, and 427Hz AC.

    2. Main technical performance:

    Class 2.5, splash proof and vibration resistant.

    3. Conditions of use:

    Ambient temperature: -25 ~ + 55 ℃, relative temperature: <98% RH
