ALM 48 PRODUCT OVERVIEW

Especially for those who require a economical transmitter with high accuracy we have developed the ALM series of transmitters. 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 the transmitters of the ALM-series easy to install and you will find an amazing accuracy on all models. Therefore, the ALM-series delivers you great value for money.

Analogue 2-wire headmount economical transmitter ALM 48 Version
The ALM 48 gives you the possibility to select any range which doesn't necessarily have to begin at 0°C. This free scaleable Railmount Transmitter has an optional extra Zero Shift. This gives you the option to select the ZERO between the ranges mentioned.

All transmitters can be fine adjusted with multi-turn potentiometers

ALM48 features
• Analogue transmitter
• Easy scalable
• High accuracy
• Rugged epoxy coated housing
• Temperature linear output
• 5 Year warranty
