Recorders / Loggers Hybrid Recorders BH Series Hybrid Recorders     The BH Series is easy-to-operate hybrid recorders to record a variety of information in analog and digital formats on a 180mm wide chart. Dot-printing types and pen-writing types are available. The recorders are provided with the scale plate conforming to its input types and measuring inputs to be able to read measured values directly, and also these values are indicated on the digital display. The compact BH Series recorders have depth of only 195mm (dot-printing type and 1-pen type) which makes them suitable for space sensitive installations including panel mounting. Features Ready to run immediately As the recorders are preset to meet individual customer specifications and precise application requirements, the recorders start indicating and recording as soon as they are switched on. Displays for accuracy and simplicity Measured values can be read at a glance, directly from the scale plate whilst a digital display clearly indicates measured values, alarm settings and chart speed together with a range of other information. Compact and easy to install The BH recorders are designed for use in applications where space is at a premium. With a reduced depth of 195mm (dot-printing type and 1-pen type) and weighing 7.0kg (dot-printing type), the instruments are ideally suited for panel mounting installations. Detachable terminal board for easy wiring A detachable terminal board is provided to enable convenient on-site connection of the cable. Abundant options Abundant options including communications interfaces (RS-422A, RS-232C or RS-485), external drive and alarm outputs are available. CE(option) The models complying with CE are available.
