Isolation seals protect pressure transmitters, while faithfully transferring pressure signals from difficult fluids and enhancing measurement of variables derived from pressure, such as flow rate, level and density. They keep the measured fluid from directly contacting the transmitter diaphragm, but respond quickly and accurately to changes in pressure or differential pressure.

|ACCURATE, ROBUST PRESSURE TRANSMITTER
Tel-Tru pressure transmitters are accurate, robust and built to last. Available options include pressure ranges from vacuum to 100,000 psi; accuracy grades from ±0.50% to 0.10%; and 4-20mA or voltage outputs. Each unit ships with a calibration report. Models are constructed of all-welded 17-4PH stainless steel or 316L stainless steel-wetted materials. Certified explosion-proof configurations available.
|SMART DIFFERENTIAL PRESSURE TRANSMITTER
ST 3000 Series 900 differential pressure transmitters bring proven smart technology to pressure measurement applications from furnace combustion airflow rate to hydrostatic tank gauging. They can be used with any primary flow element to provide repeatable flow measurement, and offer greater turndown ratio than conventional transmitters. They can be used hin azardous environments.

|PRO PRESSURE GUAGES
ProSense mechanical-dial pressure gauges use Bourdon tube sensing elements and do not require any external power sources to operate. Center back-mount and lower-mount cases are available in durable steel or stainless steel and either dry or liquid-brass wetted parts are suitable for air, oil, or water applications while stainless steel wetted parts are available for corrosive applications.
|PORTABLE PRESSURE CALIBRATOR
The PPC P/H Dual portable pressure calibrator with built-in hand pumps offer both pneumatic and hydraulic calibration. It is ideal for checking the calibration of pressure, differential pressure gauges, control values, pressure transmitters, pressure transducers and receiver gauges. Pneumatic range is -0.85 bar to 20 bar (to 300 PSI); hydraulic range is 0 bar to 400 bar (to 6,000 PSI).
