Bentley monitor 1900/65A

Bentley monitor 1900/65A

The 1900/65 is a flexible, low-cost system designed to continuously monitor and protect general-purpose or non-critical equipment in multiple industries and applications.

earnings
It is a low cost continuous online protection system compared with traditional frame system
The circuit design is the same as that used in the 3500 and 3300 monitoring systems
The 8-channel monitor provides a greater number and variety of inputs than other 1900 series monitors
With small size, flexible installation options and configuration software, the monitor can be easily installed and configured. The monitor can be applied alone or in conjunction with an optional display device to indicate all channels and variables locally
The display unit can be mounted directly on the monitor or separately, connected to the monitor via a single cable up to 250 feet from the monitor
It is particularly suitable for stand-alone applications, slide-mounted applications and assembly machinery applications and can be designed for assembly into low-cost OEM complete sets

Functional/technical specifications
Integrated, individually mounted monitor
Continuous monitoring and protection for automatic shutdown applications 4-channel vibration inputs (2-wire and 3-wire speed and acceleration sensors, as well as BentlyNevada eddy current sensors)
Up to 4 variables per channel, with independent integration and filtering control Certain variables have filtering with up to eight poles
24-bit A/D converter, 25 kHz bandwidth
4 channel temperature input CE, “Type K and T thermocouples)
Level 2 alarm – ALERT and DANGER
6 configurable relays with voting logic
Buffer sensor output -4 monitor output, 1 display output
4 configurable 4-20 mA logger outputs, individually applied configuration software receives 18 to 36Vdc power supply; A 110/220Vac external power supply is available
It can be installed with DIN rail brackets or mounted siding
Compact – its dimensions are (inches):
– Monitor :7.75×5.88×2.93
– Display device :7.75×5.03×1.29
– Monitor with display device :7.75×5.88×3.85
Optional fiberglass guard, or steel protective door (for panel mounting) to meet environmental protection installation requirements and IP65
Hazardous area permits to be approved, including CSA(Class 1 Zone 2 – although the monitor cannot be installed in Class 1, it supports sensors installed in Zone 1 through insulation and barriers), ATEX(Zone 2), CE and GOST(IEC Ex)
