ALM 42 PRODUCT OVERVIEW

Especially for those who require a economical transmitter with high accuracy we have developed the ALM series. This series is limited to four different models, yet covering the entire range of MilliVolts, Pt100 and Thermocouples K, J and T. You will find an easy to install transmitter and amazing accuracy on all models.

Analogue 2-wire headmount economical transmitter ALM - 42 Version
On this device you can easily select any of the ranges yourself (see table), just by making a solder link on top of the transmitter.

The ALM 42 is a High Quality Headmounting Transmitter; Free Scalable over the entire range of sensors starting at -50°C.

All transmitters can be fine adjusted with multi-turn potentiometers.

ALM42 features
• Analogue transmitter
• Free scalable
• High accuracy
• Rugged epoxy coated housing
• Temperature linear output (Pt100 version)
• 5 Year warranty
