Glimpse of the future

Crystal Ball

Let's take a look in our crystal ball to see what the future holds at Monnit?

Monnit's development team is hard at work developing a new Wireless Inventory Management Sensor. The Inventory Management sensor uses a soft pot potentiometer to detect when pressure is applied to the top of the sensor ribbon. The sensor can detect and send an alert when inventories are getting low. This new addition to the Monnit product lineup should be available in the near future. If you would like to learn more about this product or be notified when it becomes available, please email us at sales@monnit.com.

Boat Monitoring Solutions

Remote Boat Monitoring

There are numerous things you want to know about your boat when you are not there. Boat bilge pump failure can be catastrophic when it comes to your boat or watercraft staying afloat. Maybe you want to go out on the boat this weekend, do you know if the battery is still holding a charge? Monnit wireless sensors can let you know when an issue arise.

You want to know immediately so you can take care of problems before damage occurs or your boat submerges. With Monnit wireless water sensors you can know if the water in the bilge reaches a certain level and pump has not turned on indicating a pump issue. Wireless battery health sensors can let you know the amount of charge left on the boat battery, so you never have to worry about dead batteries.

Tech Tip of the Month

Installing a Monnit

Wireless Pressure Sensor

The Monnit Wireless Pressure Sensor is capable of measuring gas, liquid or vapor pressures from 0-160 PSI. This solution uses a combination pressure gauge / transducer interfaced to a Monnit wireless radio. It is suitable for any application capable of using a bourdon-tube based pressure gauge. The use of pressure snubbers, pulsation dampeners, and other appropriate devices can increase the range of applications available to pressure gauges. It is a prudent practice to use these items in any type of precision pressure instrument.

Do not tighten using the case

When installing and tightening the gauge, apply a wrench to the wrench flats located just above the threaded portion of the pressure fitting only. DO NOT tighten by using the gauge case housing, even by hand, as this may damage the unit or cause a calibration shift.

Suitable Sealing Method on Threads

For gauges with NPT type pressure fittings, apply Teflon tape or an equivalent appropriate sealant to the threads before installing to ensure a leak free connection. Even a very small leak may cause an inaccurate reading.

Vibration and Pulsation

The unit can withstand normal gauge vibration without damage or significant output effects. However, it is a good practice to mount the pressure gauge where vibration is minimized. In addition, it is a good practice to use an appropriate throttling device to decrease the effects of more severe pressure pulsation and/or vibration on pointer movement, including throttling screws, pulsation dampeners, elastomeric bladders and pressure snubbers.

Adjustment of Zero and Span

Adjustment of zero and span requires a specific factory procedure and pressure calibration standards. Do not attempt to do this without approval from the factory to avoid voiding the warranty.

Connecting Power to The Pressure Sensor

Connecting power to a Monnit wireless pressure sensor Take care when connecting the power source to the Monnit wireless pressure sensor. The grey cable connects the pressure gauge to the wireless radio. The two wires coming out of the wireless tranceiver require 12-32 VDC power which is passed to the pressure gauge / transducer to enable operation.

Connect the positive side of the 12-32 VDC supply power to the red lead wire and the negative side to the black lead wire.

Note: The wireless radio requires 3 VDC and is powered by either a coin cell battery, 2 AA batteries or a single 3V AA battery, depending on sensor platform. Batteries are included with the sensor when purchased.
