HT-400 Strain Gain
Helm HT-400 Features:
- Measures Tension or Compression
|
- Industry proven since 1968
|
- Simple, trouble free installation
|
- Interfaces with any Helm monitoring system
|
- High output "strain gage" design
|
|
The Helm HT-400 Strain Gain load sensing transducer accurately detects
strain levels on all types of metal stamping presses. Using either
drill/tap or weld/pad mounting method, the sensor is installed directly
to upright columns of straight side presses or throat area of OBI and
Gap Frame presses. When interfaced with Helm monitoring systems, linear
output of strain levels at each sensing location is displayed on digital
meters.
"Strain gages" in a 350 ohm full Wheatstone bridge circuit are used as
load sensing elements to assure long term stability and accuracy.
Manufactured under laboratory conditions, all HT-400 sensors are matched
within 1% and may be interchanged without recalibration of the press.
