Technical characteristics of the instrument ammeters M1740-M1, voltmeters, M1740-M1, M1740-M1 milliammeter:
Instruments used to measure identical parameters and are intended primarily for use with transducers (sensors), GSP, having outputs DC.
Instruments M1740-M1 ammeter, voltmeter M1740-M1, M1740-M1 milliammeter have color filters, through which in the case of deviations of monitored parameters outside the preset range of the light color of the pointer changes, thus signaling a violation occurs.
Instruments used in ambient temperatures from -30 º C to +50 ° C and relative humidity from 30% to 80% (over temperature) and relative humidity up to 90% (at 30 ° C).
Instruments M1740-M1 ammeter, voltmeter M1740-M1, M1740-M1 milliammeter produced in tropical version, designed for operation at ambient temperatures from -10 º C to +55 ° C and relative humidity of 95% (M1740-M1T).
In terms of resistance to mechanical impact devices are common.
Instruments M1740-M1 ammeter, voltmeter M1740-M1, M1740-M1 milliammeter have four channels.
- Milliammeter - 0 mA-1 mA, 1 mA, 0 mA-1 mA, 0 mA-5 mA, 0 mA-5 mA-5 mA, 0 mA to 20 mA, 0 mA-20 mA to 20 mA;
- Voltmeter - 0V-1V, 1V-0V-1V, 1V-10V, 10V-0V-10V.
Class of accuracy of the instrument - 1.0.
Change the ammeter readings M1740-M1, M1740-M1 voltmeter, milliammeter M1740-M1 caused by ambient air temperature deviation from the normal (within the operating temperature) does not exceed ± 0,8% for every 10 deg, when the instrument is in a ferromagnetic shield 3mm thick - does not exceed ± 1% full scale (for devices with two-sided scale - the amount of full scale value).
Settling time voltmeters in the range of 0V-1V, 1V-0V-1V less than 3 seconds, in other bands - 2 sec.
Unit weight - 2.0 kg.
Instruments M1740-M1 ammeter, voltmeter M1740-M1, M1740-M1 milliammeter consist of die-cast casing with attached to it by one unit, which is a flat cast aluminum alloy housing with a lid and a transparent front wall.
Inside the body has four measuring mechanism of the magnetoelectric system vnutriramochnm magnet and the movable part in stretching, elements of the optical system and measuring system.
On the scale of the device M1740-M1 ammeter, voltmeter M1740-M1, M1740-M1 milliammeter designation applied measurand digitizing scale divisions on the horizontal and vertical channel numbers.
The minimum probability of failure of the device for 2,000 hours of testing not less than 0.9.
