Series: HP-TL8A
Type: Intelligent, modular signal conditioner / bridge amplifier / multi-sensor conditioner
Channels: 8 CH (modular input)
Interface: RS485, plug-and-play to a standard PC
Typical use: Dynamic load / fatigue testing for structures and machinery (bridges, buildings, aircraft, ships, vehicles, cranes, rotating equipment)
HP-TL8A uses a modular architecture where each channel is configured independently (input type, range, amplification, balancing). It supports common transducer outputs used in structural testing and industrial measurement—such as strain/bridge sensors, voltage/current outputs, temperature sensors, and more—then delivers standardized voltage outputs (±5 V / ±10 V) for downstream instruments or DAQ systems.

Q1: Can I mix sensor types on different channels?
Yes. Each channel can be configured independently, so you can combine strain/bridge, voltage, current, and temperature channels in one system.
Q2: What output does the HP-TL8A provide to my DAQ?
Standard conditioned voltage outputs are provided (typically ±5 V / ±10 V), making integration with common DAQ systems straightforward.
Q3: Do I need external bridge completion resistors for quarter/half bridge strain gauges?
Not necessarily. The unit supports bridge completion options (including quarter-bridge 120 Ω), simplifying wiring and setup.
Q4: How do I remove initial offset in strain measurement?
You can use manual balance (set offset via software) or auto balance (algorithm-based) to quickly zero channels without sacrificing range.
Q5: Is RS485 required?
RS485 is the standard control/communication interface for configuration and stable long-distance connectivity. A standard PC can be used as the host.
