Hello Sendo Sensor, I'm interested in a couple of sensors from you. I like the size of the SS122 sensors and I need a date sheet to purchase them. Also do you have a warranty on your sensors? The submersible level sensor i am looking for right now to be used in water wells. I'm not sure about the temperature but I would guess somewhere around 20C.I am looking for a custom part number because I want a pressure range of 0-35 meters and a cable length of 50meters.The power supply is not so important, I can do either 5v
There are many types of materials used for constructing pressure sensors in a variety of applications, but those made from stainless steel are considered the most reliable and durable.High Tensile strength
In hydraulic applications where pressure overloads are commonplace a stainless steel pressure sensor can withstand a high number of pressure cycles without fatigue damage.Durability and Hardness In demanding environments a high reliability and durability is required to withstand the extremes of shock
Hello sir, I am using SS634 level sensors from your company . Could you give me some example of connection sensor in 4-20mA loop ? I am not sure if I have to connect + of voltage supply to red or blue wire of sensor , i. e. if current goes from sensor from red or blue wire ? The sensor is protection against reverse polarity and is fully calibrated in two points, 4mA @ 0cm, and the 20mA @ the max(depended on the sensor).
To select the right pressure sensor for a specific application besides the pressure range first of all the type of pressure measurement has to be considered. Pressure sensors measure a certain pressure in comparison to a reference pressure and can be divided into absolute, gauge and differential devices. These terms will be explained on the basis of sendo sensor’s piezoresistive pressure sensors.
There are a number of industries in which machinery must meet stringent specifications in order to be approved for application in that area. And one of the most common of these is the food or chemical industry in which no “dead” pockets can be accepted. All sensors must be installed flush with the inside wall to ensure that machinery can be fully cleaned and no germs or bacteria can survive.
We need pressure sensors regularly, for food industry. The sensor must have a totally flush (flat) surface, I mean plain surface, without the ridge on the side，and the range we look for is near about 3 to 5 m water column. the sensor should have adjustment potentiometer for zero and span, many times at site this is needed and other companies also provide. The maximum temperature will be 85 deg C.SS402 series flush
Hello sendo sensor, I am interested in a low cost vacuum sensor similar to your SS301 series. The unit needs to measure from 0.5 Hg to a max of 18.5 Hg. The sensor is needed for a new application/product. We need to measure vacuum pressure from 0 to 20 inches of mercury. The medium we are measuring is Diesel Fuel. Working temp will vary from 60 deg. F. to 120 deg. F. Can you let us know your comments ?
Hello sendo sensor, I’m looking for a non-clog submersible pressure transducer with the follow specifications. I thought your SS122 Series submersible pressure transducer looked like a good bases for the transducer. Pressure Transducer Specifications
· Non-Clogging (Waste Water Application)
· 0’ - 30’ (Ft.) Water Colum; 0-1 BAR
· Gauge Pressure
· Turn-on electrical response time < 2ms
· Supply volt of 3VDC
· Stainless steel Construction
we are looking for industrial pressure transmitters that offer 4-20mA output signal with 25Mpa gauge pressure, the pressure connection 1/4" npt is acceptable to us. The sensors will be used in oil pressure in a hydraulic system, and also for measurement of carbon dioxide pressure. The sensors will measure relatively fast changing pressure, so we prefer to have at least 100 reading per second for each sensor. Both media and environment temperature will not excedd 40C.
Hello, we are interested in differential pressure transducer and the range should be 1 to 2 PSI, we don’t need the sensors giving the direct out put of 4-20mA. We have our own circuit to convert the signal to extracted square root and give the 4-20 mA. SS120 series is more suitable for our application, in this your range start from 35 KPa, where we are looking something lower than this, even 20 KPa will do.

4-20mA Current Loop Output - is a type of electrical signal that is used in a series circuit to provide a robust measurement signal.
Best Straight Line Accuracy - defines the limit that any pressure measurement reading will deviate from the Best Straight Line.
Ceramic Pressure Sensors - typically use diaphragms made from Alumina (Al2O3) with a screen printed thick film strain gauge circuit. Ceramic diaphragms are very inert and provide a high level of protection from aggressive chemicals.
Piezoresistive pressure sensors can be classified in terms of pressure ranges they measure, temperature ranges of operation, and most importantly the type of pressure they measure. In terms of pressure type, pressure sensors can be divided into five categories:
Absolute piezoresistive pressure transducer
This transducer measures the pressure relative to perfect vacuum pressure (0 PSI or no pressure). Atmospheric pressure, is 101.325 kPa (14.7 PSI) at sea level with reference to vacuum.
Piezoresistive pressure transducers are generally available with three types of electrical output; millivolt(mV), amplified voltage(0-10V, 0-5V, 0.5-4.5V) and 4-20mA. Below is a summary of the outputs and when they are best used.
mV Piezoresistive pressure transducers
Transducers with millivolt output are normally the most economical pressure transducers. The output of the millivolt transducer is nominally around 100mV. The actual output is directly proportional to the pressure transducer input power or excitation.
Piezoresistive pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude. Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names. let's see what sendo sensor can offer.Heavy Duty/Industrial Pressure Sensors feature a much more rugged
