TEMPERATURE GAUGES

DIGITAL TEMPETATURE GAUGE “DIGIDIAL”

"ALTOP" is first manufacturer of "DIGIDIAL" range of Digital Temperature Gauges / Digital Dial Thermometers. They are battery Operated / Main Operated Local / Remote Mounter, Accurate, Stable, Long Lasting, Lw Coast, reliale and user friendly instruments. This System Utilizes "NANOWATT" Technology and latest circuit for high grade of stability, noise immunity, repetability, and years. The resolution is 0.1oC from (-) 199.9 to (+) 199.9 and it automatically changes to 1oC above that.

"DIGIDIAL” can replace the conventional mercury-in-steel, vapor pressure / Bimetallic temperature gauges. These are a ideal blend the reliability and ruggedness of the conventional type Dial Thermometers and the accuracy and simplicity of Digital Temperature Indicators.  The most important plus point of the “DIGIDIAL” is that they can be easily calibrated, repaired by changing the stems / capillaries / Displays units etc. unlike the conventional field system dial thermometers, which as good as “Dead” when they leak/.fail.

RPM Calibration Test Rig is a Multipurpose test rig used to calibrate and test various type of speed sensor, techo-genarators a n d s p e e d / R P M instruments. The rig comprise of a DC/AC drive with mechanical drive arrangement to the gears to set the rpm of 25%, 50%, 75% and 100% of the rpm available on the AC/DC drive. Mounting arrangement is provided to mount the different type of RPM sensors like magnetic sensors, inductive sensors, capacitive sensors, optical sensors, AC techo-generators, DC techo-generators etc. which gives pulses/ current/voltage according to the speed/RPM they sense. The output is measured on a calibrated measuring instruments provided on the test panel of the rpm test rig. To calibrate /test the indicating instruments and standard calibrated rpm sensor is provided to simulate the rpm and measured on the instruments under calibration and then compare the two for calibration. The range available is 60 to 4500 RPM having accuracy of ±1 RPM. Additional instrumentation can be provided as per customer requirement measured on a calibrated measuring instruments provided on the test panel of the rpm test rig.
