1-809

Product catalog summary

Overview
The 1-809 Vibration Monitor & Transmitter is designed for monitoring and protecting critical machinery such as turbochargers, generators, industrial fans, blowers, and compressors. It features dual programmable alarms, a 4-20 mA output, selectable filtering, and buffered vibration output with three-way isolation.

Specifications

Output Mode: Measures velocity in inches per second (ips), acceleration in g’s, and displacement in mils.
Vibration Range: Programmable full-scale range.
Sensitivity: Programmable sensor sensitivity.
Frequency Range: 2 - 20,000 Hz.
Temperature Range: Operating from 0°F to +158°F (-18°C to +70°C), storage from -67°F to +185°F (-55°C to +85°C).
Humidity: 0 to 95% relative humidity (non-condensing).
Alarm Limits: Programmable from 0 to full scale with SPST Normally Open & Normally Closed options.
Analog Output: Active 4-20 mA current loop proportional to full scale.
Display: 4-digit LED with decimal point delay and alarm limit indicators.
Power: 24 VDC @ 150 mA, isolated from signal I/O and 4-20 mA output.

Features
The device includes a 4-digit LED display for vibration levels, which can be shown in user-specified units. It has a start-up trip delay of thirty seconds to prevent false alarms during start-up. The 1-809 is panel-mounted and accepts velocity or acceleration transducer inputs, filtered through a bandpass filter.

Certifications
ISO 9001:2000 and AS9100 certified. Hazardous approvals include CSA c/us Class I, Division 2, Groups A, B, C, and D, Ex nA/AEx nA IIC T4.

1-809 Vibration Monitor & Transmitter Applications • Turbochargers • Generators • Industrial Fans & Blowers • Compressors Features • Dual Programmable Alarms • 4-20 mA Output • Buffered Vibration Output • Three-way Isolation The 1-809 is a single channel Vibration Monitor designed to measure and protect critical machinery. The machinery vibration level is displayed on a 4-digit LED display. The reading can be displayed in inches per second (ips) velocity, g’s acceleration, or mils displacement. A 4-20 mA output signal is provided proportional to a pre-determined vibration level. Two alarms are provided for early warning or machine shutdown due to excessive vibration. The 1-809 is a panel-mount vibration monitor designed to accept a velocity or acceleration transducer input. The input signal is filtered via an order-specified bandpass filter with very sharp cut-off characteristics. This allows the 1-809 to track only those energies present within the filter’s band-width. The resulting vibration level is then displayed on the 4-digit LED display located on the front panel of the 1809. The display indicates the current vibration level in user-specified units, velocity (ips, peak), acceleration (g’s, peak), or displacement (mils, peak-to-peak). Two programmable alarms are provided to indicate warning when trip levels have been exceeded. A start-up trip delay of thirty seconds is available to prevent false alarms during start-up situations. The 1-809 also includes a scaled 4-20 mA output for use in PLC and DCS applications.
