AI-Tek Instruments BH1512-005 BH Series Bi-Directional Sensor
The BH Series from AI-Tek are bi-directional, zero velocity sensors that are self-calibrating to specific customer applications. These sensors provide two independent frequency outputs and a direction signal output to indicate changes in rotation direction of the sensed ferrous target.
Dual-Channel Sensing Technology
The BH Series bi-directional sensor utilizes two Hall effect sensing elements that are physically offset from each other. Each element generates a single channel of target information, identical in frequency and polarity, but offset in the time domain (phase shifted).
Operation Principle
Special circuits inside the sensor calibrate each channel to its application target, then analyze the two channels of information for phase lead/lag conditions. The direction output provides a logic 1 level for clockwise or logic 0 for counterclockwise rotation, assuming proper sensor orientation.
For applications with cable runs exceeding 500 feet, a Digital Signal Distance Amplifier (DSDA) is required.
Key Features & Specifications
High temperature range: -40°C to +125°C
Supply Tracking or TTL Compatible output options
Power on calibration
Requires special alignment
Controlled duty cycle
Fine pitch performance
Increased air gaps
Wide supply voltage range: 10-28 Vdc in single design
Special circuitry provides high level of EMI hardness
Reverse voltage protection up to -30 Vdc to prevent damage if miswired
Rugged sensors designed to meet Navy ship-board standards and European Railroad Applications
Suitable for 32 diametral pitch or coarser gear (target), the standard catalog sensors are easily applied to various sensing needs. For unique requirements not met by standard options, we will review your specifications and work with you on custom sensor design.
It is the customer's responsibility to determine whether the product is proper for customer's use and application.
