MEASUREMENT & TESTING Eliminate failures in valve control and pump displacement sensing


NewTek offers its Linear Variable Displacement Transducers (LVDTs) in an isolation tube format to ensure the highest reliable displacement feedback of hydraulic/non-hydraulic pumps and valves. The isolation tube protects the LVDT core from pressurised environments and fl uids when the sensor measures pump fl ow or valve position (open/closed). The position sensor provides electronic feedback as part of a process control system.


In the isolation tube confi guration, only the LVDT core lies inside the harsh area or media. Constructed of metal, the core can withstand exposure to a variety of fl uids and pressures so that the chance of LVDT core failure is virtually non-existent. With sensor windings in near ambient conditions, there is a low risk of unit failure. In an unlikely failure, the AC-operated LVDT is accessible without disassembling a complicated valve housing. The LVDT housing is easily replaced while the core stays inside the valve.


For customers wanting to monitor the position of a hydraulic valve stem but do not have room for a vented LVDT or the budget for hermetic feedthrough, the isolation-tube confi guration is both an economical and reliable solution. The isolation tube proves superior to venting an LVDT as there is no need to run electricals out of the sensor via a high-pressure header or feedthrough. The core can tolerate temperatures and pressure that can cause trouble for a vented LVDT.


AC-operated LVDTs are ideal for valve and pump displacement sensing as the material between the core and housing can change the sensitivity of pre-calibrated DC units in highly pressurised environments. In addition to offering a range of standard AC-LVDTs, NewTek customises sensors to accommodate a particular tube or calibrate with a smaller core so that an LVDT can fi t into smaller spaces.


The Newtek NTC600 LVDT Signal Conditioner powers AC-operated position sensors and provides a digital output in a voltage, 4-20 mA current, or RS-485 digital format. This smart signal conditioner self- diagnoses LVDT failure, disconnects, or short circuits and offers cybersecurity lockout and tamper detection.

boosts effi ciency and budget


Myron L® Controller combines accuracy,


Company’s new 900 Series Multi-Parameter Monitor/ reliability, simplicity, and fl exibility.


It’s the ideal instrument for even the most demanding water treatment applications.


Measurement capabilities include: Conductivity, Resistivity, TDS, Salinity, pH, ORP, Temperature, mV input, Flow/Pulse, a multi- parameter 4-20/0-20 mA input, and % rejection. Standard outputs include a 0-10 VDC recorder output, a relay output, and a remote alarm output. Optional outputs include 4-20/0-20 mA, RS-485, two additional Relays and one additional remote alarm.


Accurate and reliable O2 measurement is required


to effi ciently control any combustion process. If the excess O2


after combustion is too high, energy, i.e.


fuel is wasted and the process is cooled unnecessarily. If the excess O2


is too low, higher concentrations of


unburned fuel molecules, usually Carbon monoxide, will be present in the fl ue which is destructive for the plant infrastructure and can lead to a potentially explosive gas mixture.


Enotec’s Oxitec® in situ O2 analyser has become the


industry standard due to its accuracy and exceptional robustness. Operating in some of the harshest combustion applications, the O2


sensors alone have


a service life of up to 8 years, making them more robust than any comparable product on the market. The standard Oxitec can withstand process gas temperatures up to 600°C and, with the cooling protection tube, this rises to 1600°C!


Enotec’s highly reliable sensor technology leads to direct reductions in operating costs as users avoid the usual semi-annual maintenance and sensor replacement. Enotec analysers carry a global, two-year warranty, even those operating in extreme fl ue gas conditions.


The fast response time of the sensors enables precise combustion control. Plants functioning effi ciently save resources have a longer life usually with improvements to the product, whilst ensuring operator safety and improved environmental performance. Ease of use and simple analyser construction are key: the sensor is calibrated automatically, operating data can be archived or troubleshooting achieved with the free ENOTEC Remote App. In addition many confi guration possibilities are available, enabling use in almost any process, regardless of how aggressive or demanding.


The unparalleled effi ciency and reliability of Oxitec® analysers is assured by internationally recognised certifi cations. Enotec’s analysers are ATEX certifi ed for Ex zones 1/2. The Oxitec®


5000 has successfully


passed the demanding TÜV certifi cation testing to meet the EN 15267 standard for emissions measuring systems (QAL1) as well as MCERTS and SIL2 with 1oo1 confi guration.
