When purchasing desktop DC power supplies, these parameters hide hidden costs
On the quotation sheet for benchtop DC power supplies, voltage and current are just the surface features. Ripple noise, load regulation, remote interface, and protection mechanisms often determine your subsequent hidden expenses. From the perspective of procurement insiders, let's discuss how to allocate your budget to areas that truly affect test results.
Is the vibration sensor reading fluctuating erratically? Follow these 4 steps to locate grounding and resonance issues
Is there a sudden change in the readings of the Wilcoxon PC420 series vibration sensor in the field? This article presents a four-step troubleshooting method, covering power supply circuit, grounding shielding, installation resonance, and comparative verification, to quickly identify grounding and resonance issues and reduce equipment downtime.
Is the humidity in the clean room frequently exceeding the limit? First, verify these six parameters of the temperature and humidity transmitter
The frequent alarms of temperature and humidity in clean rooms are mostly due to incorrect selection of measurement range, accuracy reference conditions, and output protocol during the selection phase. Based on the sample parameters of the S+S Regeltechnik RFTM and AFTF series, we will break down six selection indicators and three typical configuration combinations.
Did you select the wrong temperature recorder for GSP verification? Make sure to calculate these 8 parameters carefully before placing your order
The requirements for temperature recorders in the pharmaceutical and food cold chain, as well as GSP verification, are not solely about achieving accurate measurements at a single point. Instead, they hinge on whether the measurement range margin, sampling interval, number of storage points, and calibration certificate can form a closed loop. This article dissects the selection criteria and parameter calculation methods for the MadgeTech Temp1000IS and HiTemp140.
How to calculate the current-carrying and mating life of heavy-duty connectors to avoid failures
The selection of heavy-duty connectors is often hindered by three factors: current derating, insertion and extraction lifespan, and protection level. This article provides a current calculation method, lifespan evaluation dimensions, and parameter comparisons for the Han® series, helping engineers avoid on-site failures.
"Power off and lose position, power on and return to zero? When selecting absolute or incremental encoders, consider these five key differences first."
After the incremental encoder is powered off, its position resets to zero, and it needs to return to zero every time it is powered on, posing downtime and safety hazards in long-stroke and multi-axis scenarios. The Fenac FNC series absolute value encoder maintains its position during power-off in single/multiple turns and supports SSI/BISS/Profibus/CANopen interfaces, eliminating the need for returning to zero. This article uses a comparative table to clarify the differences in returning to zero, power-off memory, anti-interference, accuracy, and cost.
Struggling with positioning accuracy issues? Selection and error control of internal parameters for inductive (eddy current) displacement sensors
Machine tools, hydraulic systems, and injection molding production lines often experience positioning drift due to wear from contact measurement or interference from oil contamination. This article delves into the working principle, key parameters, and selection logic of esitron inductive (eddy current) displacement sensors, aiming to assist engineers in mastering the key points of error control in non-contact measurement.
