DP 400 mobile – Mobile Dew Point Measurement with Pressure Sensor
For measurement of all humidity parameters under pressure up to 16 bar. The portable dew point meter with integrated, rechargeable battery has been developed especially for the eld use. Besides a highly precise dew point sensor the device also contains a precise pressure sensor up to 16 bar. So in addition to the dew point in °Ctd, the temperature in °C and the line pressure in bar also further moisture parameters (% RH, mg/m3, g/m3) as well as pressure-dependent measuring values (g/kg, ppm v/v, atm. dew point °C) can be calculated.
FA 510/515 – Dew point sensor for refrigeration dryers
The proven FA 510 dew point sensor is now available with an IO-Link interface . The IO-Link interface enables easy integration of dew point measurement in front of machines and systems. Optionally available with integrated pressure sensors . Monitoring a compressed air refrigeration dryer is crucial for increasing energy efficiency, ensuring product quality, preventing damage to machines, recognising maintenance requirements and achieving cost savings. This contributes to the smooth functioning of compressed air systems in various industrial applications. The sensor technology and evaluation electronics of our sensors have undergone continuous improvement. This implies an increased precision at varying ambient temperatures and a higher signal resolution of the sensor. Similar to their predecessor models, the new dew point sensors are characterised by long-lasting, stable and reliable measurement results. The sensor element is insensitive to condensation and is protected from direct contact with contaminated particles by the stainless steel sintered cap.
Leak detector LD 450
If gases escape through leaks in pressurized pipe systems (e.g. non-tight screwed connections, corrosions and so on), ultrasonic noises are generated. By means of LD 450, even the smallest leakages which cannot be heard by the human ear and which are not visible due to their size can be detected even from distances of several meters. LD 450 transforms the inaudible signals into a frequency which can be identified by human beings. By means of the comfortable soundproof headset, these noises can be detected even in extremely noisy environments. The LD 450 leak detector is the advancement of the proven LD 300 and LD 400 and it impresses with its significantly refined sensor technology and its improved support in the tracing of leaks. By means of the integrated laser pointer, which serves for target heading, the leak can be localised more accurately. Through the use of a specially designed acoustic trumpet, a better bundling of the sound waves is achieved. This trumpet acts like a directional microphone, which bundles ultrasonic waves and thus improves the acoustic behavior. Due to the special design of the acoustic trumpet, the use of the laser pointer is not hindered. The LD 450 meets the requirements of class I instruments for the norm “Standard Test Method for Leaks with Ultrasound” (ASTM Int. - E1002-05)
