Next Step Solid State reference
- eliminates poisoning, pumping and plugging
Operating temperatures up to 140 °C (284 °F)
- the highest glass temperature limit on the market
Operating pressures up to 21 bar (300 psi) and higher
- the highest pressure limit on the market
Durable electrodes
- The TB(X)5 electrode design eliminates failures due to thermal stress caused by rapid temperature excursions. Unlike other sensors that use a large inner air bubble for expansion absorption, TB(X)5 electrodes use a unique inner plunger; providing more effective protection against temperature fluctuations.
The electrodes are available in several measuring element types ensuring greatest process optimization
