Product Summary
ES Systems has developed a series of medium isolated pressure sensors suitable for
applications with harsh environmental conditions where resistance to corrosive fluids or gases
is required. Each sensor integrates a MEMS capacitive pressure sensor die, and a CMOS ASIC
for the signal conditioning. The MEMS pressure sensor dies are underpinned by ES Systems’
innovative microfabrication process for silicon capacitive sensors.
The capacitive pressure sensor dies integrated into the medium isolated pressure systems
provide state-of-the-art accuracy and resolution, excellent long-term stability combined with
very good repeatability and hysteresis. The total overall error including thermal offsets is lower
than ±0.25% FS.
The ESCP-MIS1 is a family of pressure sensors in the standard Ø19 stainless steel 316L capsule.
In this type of sensors, the pressure is transferred hydraulically to the hermetically sealed
sensing element through the oil used to fill the cavity between the sensing element and the
stainless steel diaphragm. The pressure capsule interface is either I2C, SPI or analog. The
sensors are provided calibrated and compensated at various temperature and pressure
ranges from 10 bara to 350 bara. Custom materials like Hastelloy or Titanium are available
upon request.

1. Total Error Band
Total Error Band (TEB) is a single specification that includes all possible sources of error in a pressure measurement.
TEB should not be confused with accuracy, which is actually a component of TEB. TEB is the worst error that the sensor
could experience. The TEB specification on a datasheet may be confusing. ES Systems uses the TEB specification in its
datasheet because it is the most comprehensive measurement of a sensor’s true accuracy. ES Systems also provides
the accuracy specification in order to provide a common comparison with competitors’ literature that does not use the
TEB specification.

pressure is returned to the operating pressure range. Exposure to higher pressures may cause permanent damage to
the product. Unless otherwise specified this applies to all available pressure ports at any temperature with the operat-
ing temperature range

8. Data & Register Description
The ESCP-MIS1 sensors provide measurement and status data. The measurement data are
Pressure and Temperature. The data are stored in specific data registers as described
below. The readout is performed by using multibyte read transactions. Both I2C and SPI
communication share the same structure. First byte is the register address which defines the
appropriate register to be written/read and then follows the payload in either direction. The
difference between the two serial interfaces is that in I2C version the user need to address
ESCP-MIS1 device and confirm each byte reception/transmit by receiving an ack after each
transaction.
Result Registers [0x0X]
After every conversion is completed, based on the programed rate and data output, ECSP-
MIS1 sensor updates the corresponding data registers values. Data are in IEEE-754 floating
point format (32bit) and are returned in MSB first sequence.

Address 0x01 holds the pressure result in bars. The lowest and highest value depends on the
pressure range of the sensor and cannot exceed the maximum range. Over and under
pressure conditions are indicated in status register (see the corresponding register 0x13).
An example of a pressure measurement is:
Calibrated Pressure Byte 1 = 0x40
Calibrated Pressure Byte 2 = 0xAB
Calibrated Pressure Byte 3 = 0x85
Calibrated Pressure Byte 4 = 0x1E
6/19
Datasheet ESCP-MIS1
The result is represented in the IEEE 754 format and any device that has a IEEE 754 compatible
arithmetic unit does not need to convert it.
IEEE 754 float format conversion:
IEEE 754 format consists of 3 parts: the sign bit (bit 32), exponent part (bits 30:23), mantissa or
fractional part (bits 22:0) as shown in the example above:
The sign bit (s) represents the sign of the number and it is positive (+) for 0 and negative (-) for
1. For the absolute value of the number we need to calculate the mantissa and the exponent
part. The 8 bits of the exponent part are translated as an unsigned integer ranging from 0 to
255 with offset 127. For the mantissa part we need to calculate the above sum:
After calculating the above the final result is given by the equation:
In the example for 0x40AB851E (b0100 0000 1010 1011 1000 0101 0001 1110) we get:
Sign = 0,
Exponent = 129,
Mantissa = 1.33999991417
Finally pressure measured is P = + 1.33999991417 X 2 130-127 = 5.36 bar
Embedded software conversion:
In practice, the user should just cast the received bytes from registers 0x0X to a float variable
with IEEE 754 format and the calculations will be done automatically by the compiler.

At power on reset, the sensor needs 30ms to initialize. After that time the device is ready to
communicate as an I2C slave device with 7-bit address 0x28.
If the master device transmits the selected sensor 7-bit address (0x50) with R/W bit set, and
the appropriate register address, the sensor returns the result specified in the previous
section after acknowledging (ACK) by holding the SDA line low. In order for the master to
receive the data requested, should send 8 clock pulses for each data byte and provide an
acknowledge bit at the 9th clock cycle by holding the SDA line low. When the last byte is
received a stop condition is issued from the master indicating the termination of the
transaction.
An example of such a transaction is shown below.

I2C communication example
A typical use case is presented bellow. The user powers up the ESCP-MIS1 either by applying
power to the system or by sending a reset command to the device. After initializing, the user
reads the device’s serial number and firmware version and reads the pressure and
temperature values periodically. At any time the user can read the status register to check that
the sensor is converting and the maximum or minimum pressure limit is not exceeded

SPI serial peripheral interface follows the same register mapping as described in section 8. The
sensor uses mode 0 SPI with CPOL = 0 and CPHA = 0.
The SPI communication requires to send, via the MOSI signal, the address to read and then
the following clock pulses will produce the required result on the MISO line. After the address
setting the slave requires a tsetup time before issuing the data clock pulses in order to fetch the
data to output buffer. The CS line should be driven low and kept low during the transaction.
The following example describe the SPI transactions for reading the pressure output of the

15. Instructions of Mounting
O-ring option
Recommended installation for pressure sensor with FKM O-ring for temperature range –20oC
to +125oC. Working temperature range should be taken into account when designing the
installation cavity. During installation, O-ring should be lubricated with suitable grease (In O2
applications do no not use any grease).
Weld option
Recommended installation for pressure sensor with laser welding
16. Instructions of Operation
The ESCP-MIS1 sensor features digital temperature compensation. The temperature is
measured on the MEMS element by an on-chip temperature sensor. This data is fed to a
compensation circuit that is also integrated on the microprocessor. Thus, no external
temperature compensation is necessary.
Sensor Handling
The ESCP-MIS1 sensor is designed to be robust and shock resistant. Nevertheless, the
accuracy of the high-precision ESCP-MIS1 can be degraded by rough handling. ES Systems
does not guarantee proper operation in case of improper handling.
