Franklin Lakes, NJ — Digital electronics and precision engineering contribute to the small size of the latest addition to Process Sensor Corp’s IR thermometer line.
The DS-40N and DG-40N series of stainless steel pyrometers are 124.5mm long overall by M40×1.5 threaded diameter, operate in a current loop powered mode to produce a linear 4 to 20mA output over selected temperature ranges from an overall span of 250 to 2500°C in two models.
In a 4 wire mode, the sensor also offers green LED, illuminating the exact target size, or laser aiming.
Depending on the model, either DS-40N or DG-40N, and temperature range, selected optics provide small target, close focus e.g. 1.2mm diameter at 210mm distance, or extended focus out to 4m with a 20mm diameter target.
A USB connection gives access to PC adjustments of such parameters as emissivity, response time, temperature sub-range and peak picker, with supplied software.
These non-contact sensor will operate in ambient temperatures up to 70°C without cooling. Adding the optional cooling and lens-purging jacket can extend ambient temperatures higher to 200°C .
The Model DS-40N has a spectral response of 0.8 to 1.1µm, and the DG-40N 1.5µm to 1.8µm, for minimum vulnerability to variable target emissivity, and to optimize the effective emissivity of low radiance targets.
The temperature ranges, optics, rugged construction and signal processing capability will appeal to users in the Steel, Ceramics and Glass Industries, Cement and Refractory manufacture, Induction Heating and Sintering operations.
Process Sensor “PSC Spot Software” supports sensor set-up, multi-tasking, graphic display of temperature trends, and data logging, and in general allows the user to customize the sensor to the application.
