Intrinsically Safe

For an OEM, level measurement in easy places is, well, easy. In fact, in some places, it’s so easy a float switch can do it (well, several hundred float switches). But we’re not here to talk about those places today. We’re going to look at continuous level measurement with harsh chemicals. And in explosive atmospheres. And the availability to meet OEM and system-integrator needs. That’s right, we looking at the Intrinsically Safe, Chemically Resistant MPI-E Chemical Float Level Transmitter.

It’s Titanium. It’s bulletproof. Right?

Okay, perhaps our MPI-T isn’t literally bulletproof, but then again neither is Sia. And while the bulletproof metaphor nearly works for APG’s new MPI-T Intrinsically Safe, Titanium Stem Magnetostrictive Float Level Transmitter, perhaps an even better one is that of dodging bullets. There are all sorts of bullets related to crude oil storage just waiting to kill your level measurement systems, but the MPI-T can help you dodge those bullets.

No Jedi mind-tricks necessary here. APG’s new MPI-F Intrinsically Safe Flexible Stem Magnetostrictive Level Transmitter is just the flexible probe you’ve been looking for. The MPI-F is flexible, intrinsically safe, and can be inherently safe, and when we say flexible, we aren’t just referring to the stem. The safety value of the MPI-F extends beyond protected operation in hazardous locations.

When it comes to choosing a liquid level sensor, the one that gives you the most advantages is the one you are going to choose. Whether the advantage is in price, availability, technical performance and specifications, or durability and reliability, the sensor that checks off the most boxes is going to win. The new MPI-E and MPI-R Intrinsically Safe Magnetostrictive Float Level Transmitters offer quite a nice pile of advantages, from quality design and manufacturing to precision measurements and configurable outputs. Let’s take a look at three specific advantages the MPI-E/R gives you.

When the Eagles were telling everyone to “Take It Easy,” they had no idea the MDI would make level measurement in hazardous locations so easy. The MDI, APG’s new Intrinsically Safe Modbus Display and Controller, is the basis for a Self-Contained, Intrinsically Safe, Modbus Level Measurement System, and everything about it is easy. Easy to set up and use, easy to connect and install, and easy to match with a Modbus slave sensor.

If you were to look up “versatile” in the dictionary, you might find a picture of APG’s new MNU IS Intrinsically Safe Modbus Ultrasonic Sensor. Ok, you might not yet, but you should, and soon. With features like APG’s new QuickMode, global Class I, Division 1 hazardous location certification, and RS-485/Modbus RTU standard on every unit, the new MNU IS is capable of handling just about any level measurement situation. Let’s take a look.

In a recent cooperation between NIOSH, the government agency for researching work-related injury and illness, and private partners in drilling and well servicing found that workers involved in flowback operations where exposed to elevated levels of benzene, a known carcinogen.

The preliminary results of their study were published on the CDC blog last month. The study was conducted by taking urine samples of workers at the end of their shift. The study also included, “short-term and full-shift personal breathing zone and area air sampling for exposures to benzene and other hydrocarbons.”

Level and pressure sensors for hazardous areas are designed in a number of ways to prevent ignition of an explosive mixture. Two of the more popular methods for low-power instrumentation are intrinsically safe and non-incendive.

Both limit power significantly, ensuring there is never enough energy to produce a spark and ignite a dangerous gas or dust mixture. In fact, there is more that is the same between the two protection methods than there is different. So, to help you know when & where they’re appropriate, we will focus on the differences.
